From the road from Blaenavon to Abergavenny, take the road to the left, just before
the Keeper's Pond (or on the right, just after the Keeper's Pond when coming from
Abergavenny). Parking is on the left after just over 1 km, on a large concreted area
opposite the Lamb and Fox public house. If the car park is blocked, ask at the Lamb and Fox
if you can park in their carpark instead.

From here, continue down the road towards the Pwll Du Adventure Centre, a white building
on the right side of the road. A stream starts at the adventure centre, running downhill to its left, cutting through a coal tip.
Cross the stile into the stream's fenced enclosure, then ford the stream, and follow it downhill to a fence.
Cross the fence then proceed, to the right of the stream, down an obvious but very steep path.
This leads directly to the entrance, a small gated phreatic tube at the foot of a small outcrop.

Access

The cave is gated. Access is controlled by the Pwll Du Cave Management Group
and should be applied for in writing to Sue Mabbett, 2 Garth Close, Morganstown,
Cardiff CF15 8LF, on club letterheaded paper.
Please enclose a Royal Mail stamp for a large envelope and an address label for yourself.
Applications are rarely refused. The access officer may also be contacted by email
using the details on the committee site.

The gate is located at the entrance to the cave, and uses a keyed lock.
A log book (for logging trips and for recording damage to the cave or information of scientific
interest) is placed at Cairn Junction, at the end of the Entrance Series.

Please do use the log book and sign-in; remember, your life or that of a friend could
depend on it!

Note that the use and digging of
other entrances is prohibited by the landowner and the cave management group.
Use of other entrances puts the conservation of the cave at risk, and risks access being
denied completely to all cavers.

Pwll Du Cave Management Group

This group, formally constituted on October 13 1996, and comprising representatives
of clubs involved with Ogof Draenen together with the Cambrian Caving Council, will
administer future access to the cave and conservation policy.

Fixed Aids

Although there are many fixed aids such as handlines, ladders and hangers in the cave, the Pwll Du Cave Management Group wish to stress
that only a few of these are officially maintained by the group. Cavers should treat all other fixed aids as unmaintained or suspect.
The use of any fixed aids is done at the user's own risk. The following list of fixed aids are maintained by the Pwll Du Cave Management Group:

Conservation

All visitors to Ogof Draenen are requested to respect the marker tapes which have
been laid in many parts of the cave, as these are there to help protect the formations
and occasionally the floor, in order to preserve the cave environment. However, due to
the rate of exploration in the cave, it is not always possible to keep up with the taping
and some calcite and gypsum formations, mud formations and guano deposits are
currently unprotected. Visitors in unfamiliar territory or new extensions should be alert
to this fact and exercise an appropriate level of care.

Ogof Draenen is also inhabited by bats. It is a criminal offence to interfere with bats
(note that this would include photographing them without a license, or remaining in a roosting
area long enough to change the temperature significantly),
so please avoid them wherever possible. Furthermore, please note that the use of
hexamine for heating and cooking produces harmful by-products (read the packaging!)
which can disturb, or even poison bats. Thus, although the use of hexamine in the cave
is not prohibited, any disturbance or harm caused to the bats would be considered a
criminal offence, so please avoid using it.

As in the nearby Llangattock caves, the use of carbide and the smoking of cigarettes in
Ogof Draenen is prohibited.

Flooding Characteristics

Most of Ogof Draenen can be passed during high water conditions, with the following known exceptions:

The ducks in Agent Blorenge and Y Gwter Fawr can sump in wet weather.

The section of the Beyond A Choke streamway before the chokes can become
hazardous in high water.

The Western extremities of Blorens Inlet can become very "sporting" after
heavy rain but Blorenge Inlet appears not to change very much.

In Dollimore Series, the normally ankle-to-knee depth water in Out Of The Blue
can become chest deep very rapidly, with less than a day of rainfall, and Into The Black
can pond up to completely cover the mud banks around Yellow Van Passage.

Following several days of rain, a few hours worth of heavy rain will cause serious
flooding throughout the early portion of the cave:

In Upstream Passage, the water can be seen to rise a few cms a minute, causing the low
sections at its upstream end to sump.

The 4m roped climb in the entrance series becomes a waterfall with a significant
volume of water. However, the entire entrance series can be passed, including that climb,
although it is extremely unpleasant.

Overview

Ogof Draenen is the second longest cave in Great Britain and contains some of the
largest cave passage in the country including, in War of the Worlds and Dollimore Series, what is probably
the second largest passage in Britain. It is also very complex in places. Visitors are
strongly advised to carry a survey and this description, or to go with someone who
knows the cave well. There are also many loose boulders to traverse and the
danger these pose is often heightened by a slick covering of mud. For this reason
the cave can prove very tiring. The cave is not suitable for novices.

As the cave is extended, it is obviously becoming possible to do longer and longer
trips. The duration of some of these trips should not be underestimated; not only
can they prove extremely tiring, but serious consideration should be given to the
need for extra lamp batteries. There are now several reports of inward bound cavers
donating spare lights/batteries to outward bound cavers!

Roughly speaking, the cave is shaped like a letter "K" (although from the survey
the shape appears more like a lower case "h"), with the backbone aligned
northwest-southeast and the entrance at the junction of the
two arms with the backbone. The cave may therefore be conveniently divided into six
"areas" - the main routes through these areas are highlighted:

Description

1. The Entrance

Entrance Series to Cairn Junction

Following the small entrance passage, a climb down in the floor is reached
after a few metres. This descends down to two scaffolded shafts. From the bottom
of these, a low crawl leads off. The crawl widens into a small
enlargement and a stream is seen at the far end of this. The stream is followed
through a flat-out crawl, and down a tight, wet, hole in the floor where a further drop
lands at the head of an 8 m deep scaffolded shaft. At the bottom of this shaft is a
chamber. From the chamber, two passages lead off:1) a tall rift straight ahead, and
2) a low crawl to the right (the usual route).

1) The rift is a traverse, Darling Rifts, with several oxbows and side passages leading off. Just before the rift
closes down, after about 75 m, a passage doubles back on the right. This is the
Pitch Bypass but an obvious continuation of the rift is in the floor assisted by a fixed
handline. This leads down to a chamber with a stream running down the opposite
wall and disappearing in the floor. On entering the chamber, a large side passage to
the right can be followed to a 20 m pitch, Big Bang Pitch (hangers and a tether are placed above
the pitch, backup to a large slab, deviation part way down).

Beyond the pitch, a small series of passages can be accessed which consist of two oxbows, the first called Gyracanthus Loop,
and a passage, Psammodus Passage, leading back through a choke into the chamber before the pitch. These contain
many fossil dorsil spines of sharks (ctenacanthus) which appear as black
objects with a U-shaped cross-section protruding from the walls. Other loose shark
fossils collected from the floor of the same area were identified as the spine of
gyracanthus, and the tooth plate of psammodus. The samples of the gyracanthus spine and
psammodus tooth plate are located in the
National Museum Cardiff,
available for viewing on request - advance booking required. For further details,
see the BCRA publication "Cave Science", Vol 30 (1) pp 33 - 36.

Big Bang Pitch comes out in the roof of the large Upstream Passage, which is
littered with boulders for almost its entire length. A stream runs under the
boulders. The usual way on is downstream (when facing the hangers at the top
of the pitch this would be to the left - in the direction of a large mud and sand slope).
Not too far on a cairn is seen. This is Cairn Junction. The side passage to the right
is the other way in.

2) The crawl is only a few metres long and leads very quickly into an enlargement. In
the floor of the enlargement, there is a short awkward rift which doubles back on
itself to regain the stream in Spare Rib. A dead-end side passage leads off
to the right, ascending tight climbs to end at a choke.
Spare Rib is followed downstream until, after two small cascades, it
disappears in the floor of a chamber. A large boulder blocks the view of the
main part of the chamber.

From here three passages lead off: 1) to the left of the chamber a rift is the other
end of the Pitch Bypass passage from the rift traverse, 2) straight ahead and along
a high rift is a comfortable oxbow to the third passage (although this route is slower)
with a few holes down into it (one such hole contains some formations which would
easily be damaged by the passage of cavers overhead so please take care if using
this route), and 3) a crawl to the right (the second passage follows
approximately the same path as this passage). The usual route is to start along the crawl,
then switch to the high rift at a taped-off formation.

The second and third passages can be followed into a larger passage and this can
then be followed to two climbs, a 4 m roped climb and a further, unroped, but
smaller one. Shortly after, a climb up some boulders leads immediately to Cairn
Junction.

Strawberry Passage

Cavers are requested not to enter Strawberry Passage, and to take extreme care if
they do visit it, in order to protect the formations, some of which are in very
vulnerable positions. Some sections of passage have not yet been taped.

Starting from the top of an awkward slope above the 4 m roped climb in the entrance
series, the 30 m Overpass bolt traverse begins on the left-hand wall then passes to the right-hand
wall to cross over the top of Cairn Junction and enter Strawberry Passage. Depending
on how the traverse is rigged, as much as 50 m of rope and 15 hangers may be required.
From there it may be desirable to rig a 15 m ladder landing beside the cairn as the
traverse is somewhat exposed.

Strawberry Passage begins as a slope up into a narrow rift. Early on, a crawl under
the right-hand wall bypasses a taped off oxbow, and a climb up and down is required
later. Tapes mark where sediment deposits and stal are in vulnerable positions, please
pay attention to them. After about 150 m of narrow but generally walking sized rift,
there is a selection of very fine stalactites and helictites, tucked in an undercut.
Less than 100 m further on, a junction is met with a larger passage.

To the left, a taped route through a smooth but cracked mud floor quickly reaches a
dig, after passing a rift to the right. The rift, Quality Street, passes an awkward
oxbow to the left before reaching a 2 m drop. Traverse over this to protect the mud
floor and climb down a few metres beyond. The passage continues as a winding rift with
thick layers of glutinous mud on the walls. It has not been taped and so extreme care
must be taken not to damage the stal flows. In the floor, an orange calcite 'stream'
meanders gently, before filling the floor at a low section. Carefully stepping over it,
there is an oxbow that bypasses this section, but as all that lies beyond is a narrowing
passage covered in glutinous mud, it may be better to stop here.

To the right at the junction with the larger passage, the main way on continues with a
smooth cracked mud floor, passing several sections where dried crystal pools with unusual
crystal growth and calcite 'streams' cross the passage. Passing these requires careful
stepping between taped sections, without dropping mud on the formations. The problem is
made worse by the large amounts of damp mud that sticks to cavers' boots. Beyond this, a
drop down to the left reaches an inlet aven, Strawberry Falls, and a short section of streamway, which feeds
one of the inlets in Gilwern Passage. Continuing past the drop down, avens all choke before
a pool containing The Strawberries is reached. The Strawberries are a unique formation made
from hundreds of small red-orange balls of calcite, forming on the bottom of the pool
instead of the usual calcite crystals. The pool fills the entire passage and continuing
along the low and narrow passage ahead would destroy The Strawberries, so it has been left
un-entered, with a tantalising view into the passage ahead, enlarging to walking size again.

There may be hope for a bypass, but until one is found, the passage must be left unpushed.

Cairn Junction to Tea Junction

From Cairn Junction the large passage continues downstream to the right, passing
by several side passages and oxbows, up and down easy climbs and through
some shallow pools to the enormous, boulder-littered, Tea Junction. Here, a large,
although out of sight stream enters from a very large passage to the left.

From the first right turn on the way downstream to Tea Junction from Cairn Junction,
a large side passage on the left, which soon lowers to an easy crawl, can be taken.
After about 50 m a hole down to the right is the Wonderbra Bypass whilst the crawl
continues ahead. Wonderbra Bypass is a quick and much easier route than the
streamway, which emerges further downstream under a very large rock bridge,
where turning left quickly reaches Tea Junction. Avoiding the hole down, the crawl continues straight ahead as Beer Challenge
to a junction. Straight ahead closes down past a squeeze, but right leads along the
low Carpet Crawl into White Arch Passage, 150 m upstream
from Tea Junction - the way to Lamb and Fox Chamber is to the left.
When aiming for White Arch Passage, Carpet Crawl can take a little less time than
going via Wonderbra Bypass and Tea Junction, as well as being much quicker than the stream route, and makes a refreshing
change for the boulder-weary caver! Most visitors use the Wonderbra Bypass when heading towards the
Beyond A Choke Streamway, Gilwern Passage or The Score, and most visitors use Beer Challenge/Carpet Crawl when heading
up White Arch Passage.

2. The North

Upstream Passage

Heading upstream from Cairn Junction, to the left, the large passage leads past a
noisy inlet on the left and over a large dried mud bank to more large passage.
About 50 m further on from the mud bank, Big Bang Pitch can be seen entering
from the roof. The large passage continues past this, to a loose choke which is
passed at the top on the right. At this point, a dead-end side passage leads off on the right,
a narrow crawl for 30 m ending at a 7 m climb down with no way on. The choke is short and the large passage is
regained on the other side. The large passage ends after a further 100 m of
stream passage, where an inlet showers in from above and some formations can
be seen in an alcove to the right.

The way on now becomes a 3 m high but much
narrower passage. Some 40 m along here the main Upstream Passage turns right, but
ahead an originally-laddered 7 m climb (a looped rope is in place as of September 2017, which
can be used with a karabiner as a pull-through rope, a climbing belay, or a cordette) leads to
a 300 m long side passage called Ladder Passage. Ladder Passage starts small
and passes through a 25 m long low crawl before a climb up doubles back into a larger passage with
several proto-shark tooth plate fossils, which ends at a choke.
Upstream Passage continues to the right at the junction with Ladder Passage, past an
inlet, and then becomes a short crawl. This ends at a sharp turn to the right at which
point the roof once again rises to standing height. Just past here, a stream enters
from under the left wall. This can be regained by climbing into a narrow rift to the left.
This is the start of the Waterfall Series.

Upstream Passage continues beyond the way into Waterfall Series as a narrow rift,
which soon widens into a more attractive passage, ending at The Fly Cemetery choke with several stal adornments.
Shortly after the passage widens, a side rift on the left can be followed until it splits into
an upper passage ahead-left, and a lower passage ahead-right. Both passages pass through squeezes,
with the lower one only passable by extremely small cavers (despite looking larger at first).
The upper passage starts with its squeeze, which is not passable by persons of more than average build,
but could potentially be dug larger. The two passages rejoin a short distance up ahead, and
the ongoing rift is a little larger. At the next split, the lower passage ahead-right closes
down completely, while the one ahead-left becomes awkwardly narrow, turning right at a
sharp bend. A short distance further on, a larger passage appears in the floor, but is blind.
Traversing over it reaches a climb down into a larger passage with a sand and rock floor, Pen-y-Galchen Passage.
This can be followed for 150 m to a final choke, passing an extremely tight oxbow on the left, leading
between the final two corners.

Waterfall Series to Knees Up Mother Brown

At the start of the rift the only way on is to leave the stream and proceed up a series
of tight climbs until the stream is regained. Following a short section of stream
passage, a further climb over the stream leads to a waterfall beside a fixed rope (which
is not officially maintained).
The rope climb overhangs slightly and has few footholds but can be free-climbed with some difficulty if needed. It may be beneficial to send
the better climbers up first, and use a 10 m belay line for weaker climbers.
From the top of the rope the stream can be followed for 75 m to an inlet aven, and a
choke just beyond it, where treee roots can be seen among the rocks.

About 30 m along the last section of stream passage (from the top of the rope) a
small tube on the left enters a smaller inlet passage, which is the main way on. This passes several boulder
obstacles before entering an enlarged junction from which several ways lead off. The main way
on is almost directly above the way in, and is a dry passage. All of the other passages end quickly
in chokes, except one to the left, which regains the stream. The stream, Waterfall Passage, has very little to offer
despite being 175 m long, starting low and requiring several crawls in the stream early on,
while a narrow ascent of the rift accesses awkward traversing ledges from about half way along.
Where it lowers just before its terminal choke, a crawl to the right also ends at the choke.

From the enlarged junction, the main way on leads to a very
slippery climb up, assisted by another fixed rope (also not officially maintained, but
also possible to free-climb with some difficulty if needed). A belay may be useful for weaker
climbers. At the top two passages lead off. The one over the top of the aforementioned junction
choking after about 40 m, and the other being the way on (which officially has no name, but may be mistakenly
marked on some surveys as Outcast Passage, after a club that helped survey it). The way on passes by some gypsum
formations and under some low sections before reaching a sharp right hand bend.
The obvious route on becomes blocked with mud after 30 m. Instead a climb up on the
right is the real way on. This reaches a series of crawls after 40 m.

The first crawl is of varying height and ends after 70 m at a relatively easy squeeze up a slope. The
larger passage that leads on from here is short lived as a junction is met with a short crawling passage
to the left, and two passages above each other ahead. The upper passage ahead quickly becomes very tight and chokes after 20 m, but
not before it passes over a visual hole into the lower passage. The lower passage ahead, which is crawling sized, is
the way on, with some holes into the upper passage, followed by another squeeze up a slope. After some 40 m it becomes a rift of stooping proportions.
The rift is followed for over 200 m, through some small complexes (though the way on
is usually obvious), and over some easy traverses to where a climb up is forced into a
somewhat larger passage. This is choked in both directions and so the continuation of
the rift on the other side of the passage must be taken to another climb up. This leads
into a much larger passage, known as Knees Up Mother Brown to the left and Yes Passage to the right.

Knees Up Mother Brown and beyond

Knees Up Mother Brown is a phreatic passage with a flat roof and sand floor for most of its length. This
makes it possible to run the 200 m (to the left) from its junction with Waterfall
Series to its junction with Lost River Passage. Turning right on entering Lost River
Passage leads past a few oxbows before the passage degenerates and ends
after 100 m. Turning left and scrambling up a small slope up enters 6th Heaven
Chamber, with its fine collections of aragonite formations. To the right here, a low
passage enters a choke, while straight ahead, a climb through a rock window
enters another chamber which also contains a few aragonite formations.

Turning right into Yes Passage (at the junction where Knees Up Mother Brown was to the left) sees the passage roof
progressively lower to crawling height after just over 75 m. The crawl lasts for a
further 175 m. At this point, the sand on the floor turns to wet mud and the passage
enlarges to stooping height. A few metres ahead a low, muddy bedding can be seen at
head height ahead-left, while Yes Passage swings right and follows the edge of a choke
which makes up its left wall, before becoming too tight. The muddy bedding enters an enlargement in the base
of the choke. Here a route ahead and then up through the choke to the right enters the low, but wide, Padlock
Passage. To the right the passage chokes with rocks, but to the left a taped route
leads over boulders and under some low sections to a steep ramp down. At the bottom
of the ramp, the passage becomes much larger and after 50 m a deep pit develops
in the floor. Some 50 m further on the passage appears to choke. This marks the
start of Bolder Land.

Bolder Land

Warning: this whole section of cave is VERY loose and should be treated with the
utmost care and respect.

At the end of Padlock Passage, a bedding to the right and the rift in the floor ahead both contain holes down
between boulders. These enter a calcited passage within the choke running in the same
direction as Padlock Passage before entering a loose chamber. The way on is to
cross over to the left and take another small passage continuing in the same direction within the choke. This reaches
a squeeze up into a small enlargement. A climb up then leads into a loose section of passage continuing in the same direction,
staying up at roof level over a blind lower route. The route quickly enlarges
into a short section of large passage which also contains a deep but blind pit in the floor to the right. Ahead there are two
ways on.

Ahead is loose and requires a lot of faith. This route is not advised!

A better route is low and to the left. This enters a large undercut with the upper route
entering from the right, and a 5 m pit at its far end. The way on is to crawl round to the
left of the pit on a ledge and then climb up at the head of the pit. This requires
the use of a boulder that is supported by a badly shattered wall, the source of the passage's name. Take extreme care!

The passage continues as a shattered rift with several undercuts to the left. Many pits
also exist in the floor and in the undercuts, one of which has a low route leading back
into a previous undercut. At various points, it has proto-shark fossil spines (like the
ones in Raiders Passage and the Entrance Series) visible in the walls, the most
northerly known in the cave. After just over 100 m, the passage narrows
and starts to wind. A climb must then be made over a boulder pile. The climb back
down lands at the head of a 6 m deep pit.

The passage now turns right and takes on a phreatic style before reaching a small
boulder ruckle at a corner to the right. At this point the passage enters the overlying
millstone grit which has infiltrated the lower limestone beds. Ahead, in a lower section, a junction is met. The way on is up to the left
where it reaches another junction. Here the only real way on is to the right.

An area is soon reached where the only possible way on is under
a shattered roof to the left. This enters a chamber with the continuation under the wall
to the right. Ultimately this enters a terminal chamber filled with red sand run-in.

3. The South

The Beyond A Choke Streamway

When following the Round Trip or Long Round Trip, follow this section in reverse, starting at the junction with Agent Blorenge.

From Tea Junction, the streamway continues downstream to the right. After around
50 m of huge passage, a higher passage leads off ahead up a large slope. This is
Gilwern Passage, and is the way to the Galería Garimpeiros Extensions and Saint Giles Series.The Beyond A Choke streamway continues to the left.

Beyond A Choke streamway starts big and wide over boulders but narrows after a
hole down through boulders to the streambed is reached, just beyond a traverse along the right wall. Although the large
passage continues up an easy climb ahead, this is not used as it requires a 10 m
pitch to regain the stream.

After about 750 m of easy walking passage (along the streambed), interspersed
by a few easy climbs, cascades and many pools (some up to 2 m deep), some
very obvious stalactites and stalagmites are seen up to the right, with the largest stalagmite being The Sentinel. Just past here,
two chokes are encountered in quick succession. Both may be passed via semi-obvious
muddied routes starting about 4 m up each.

Beyond the chokes, the passage is narrower than before, and soon passes over a boulder pile.
A short traverse on ledges is then required while the stream flows in a narrow slot. This ends at a right bend and a small cascade.
On the far side of the plunge pool, the passage turns left again, and the main way on is to continue at stream level.
An alternative climb up the wall ahead at the left bend can be used to access a higher route continuing downstream on wedged boulders.
After some distance along these boulders, an exposed climb up the right wall leads into A Bit Of A Dive. This passage goes for
250 m to the Parrot Sump. The passage currently ends at Parrot Sump 4.

Continuing at stream level, another 300 m downstream, the Agent Blorenge streamway, the far end of the
"Round Trip", enters from the left, at The Confluence.Beyond A Choke streamway continues past this
for about another km through many areas of waist or chest deep pools, with one pool on a
corner near the end being about 2 m deep, and normally requiring a very short swim. In many areas
along here, the passage is up to 5 m wide and often the roof lowers to give the
impression that the passage is about to sump, although its final end is in the
Riflemans Chamber, where a boulder pile is reached with a high mud slope to the
left. At the top of the slope, a balcony gives a view back up the stream passage and
at the far side of the balcony on the right, a route up through a choke enters a higher
level, loose chamber with no way on. This is the present limit of the downstream
cave. From here, the water flows south for over 7 km to the Snatchwood Bridge and
Pontnewynydd risings.

The only significant side passage after Agent Blorenge is at high level on the left
shortly afterwards, Fall Out, just over 100 m long.

The Score

This is usually entered via Back Passage (see Tea Junction to Lamb and Fox Chamber
in section 5 below), but was originally accessed from the Beyond A Choke
streamway, providing the opportunity for a round trip.

Back Passage leads, via 70 m of flat-out crawling, into a chamber at the start of
Crystal Cruncher Passage. To the left is an oxbow, while the main way on is ahead,
soon passing large amounts of gypsum formations.
After 190 m of comfortable crawling/stooping, passing a small dig on the right,
a wide side passage to the right reaches a dig, and the way on is to the left.
The passage becomes walking height and more arched with even more crystal deposits than before, lowering again over the next 75 m.
At this point, it passes the short Crystal Crawl and another side
passage on the left, then swings right after 50 m to enter the main passage of The Score.
To the right it descends to mud fill, while to the left, it
continues crawling sized. After 25 m, the mud floor descends, and the passage becomes
walking sized. 50 m further on, the alternative route in via Oo Crawl joins from the
right, which is taped off at this end.

Beyond this, the passage enlarges to over 7 m square, passing several side passages over the next 130 m until the roof lowers
to just over standing height and the passage changes to a large, oval phreatic tube.
In general, the side passages at floor level are quite long, while those higher up are usually only a few metres long.
The first side passage on the left is A Bit On The Side, a 40 m crawl.
The first side passage on the right, Extra Marital Sex, contains two squeezes along its 150 m length. The
second, Suicide Squeeze, is long and extremely tight, without any reward on the other side, and is only
passable by the smallest of cavers.

Continuing along the main passage, the roof quickly rises again as the passage
enters a chamber. To the left and right are small side passages, with the one on the right being the
50 m long Shit Hole or Twll Baw. The way on is up a
small climb ahead, from where a low passage gains a short section of the larger passage.
In the floor, a taped off passage back under the way in re-enters the previous chamber through a tight squeeze.
Ahead, however, the way on closes down to a narrow crawl after 30 m. This soon enters a larger section, which swings right
and reduces in size again, to reach a junction. To the left closes down while
to the right is One Night Stand.
This continues as a narrow passage with a 30 m crawl at its start,
and reaches a squeeze after 100 m. The 2 m long squeeze is only passable by small cavers,
and starts as a body sized tube, ending after a step up into a bedding passage. The bedding is decorated with small stal
columns and helictites, which need to be carefully avoided. Within less than 50 m,
the passage ends, with a view through a hole to some calcite formations; The White Wormery.

About 260 m back from the first choke (about 20 minutes from Tea Junction) in the
Beyond A Choke streamway, a 10 m climb can be made up a muddied stal alcove
and ascending rift on the left (facing downstream) into Over The Top. This large passage leads upstream over
a hole in the floor down to the streamway and continues for 110 m, passing a crawl
at head height on the right, to another hole in the floor to the stream. Over The Top
ends after about another 150 m.

The crawl on the right, Oo Crawl, is about 275 m long. Very tight to start with, it
becomes slightly larger after about 75 m.

A further 100 m on, the roof rises to standing height with a few low sections.
This section of standing passage ends after 100 m where it enters the main passage of
The Score, having passed some delicately placed gypsum crystals (exercise care).

4. The Northwest (Gilwern Passage and beyond)

The Beyond A Choke Streamway to Forever Changed

Climbing the slope from the point at which the start of the Beyond A Choke
streamway swings left enters Gilwern Passage. This is fault-controlled (by the
same fault that controls most of the Beyond A Choke streamway) and is therefore
remarkably straight throughout. It is beautifully decorated, and great care must be
taken in some places to avoid damage, particularly by the splashing of mud, to the
formations. These are mainly gypsum crystals, which extensively cover both walls
of the passage for almost its entire length, and calcite formations which, although
not as abundant, are equally as beautiful.

From the top of the slope, Gilwern
Passage turns right with the short R.I.P. Passage behind the tapes on the left.
It quickly becomes a crawl over mud banks, just after
some formations, but it is possible to stoop in a channel on the right after a few
metres. After about 30 m, the passage enlarges at a tricky sand slide. About 20 m
further on, a large crystal pool and flowstone formation, Giles' Shirt, is seen to the right. Here the
passage lowers after a climb up but soon opens up again as an inlet comes in
from high on the left. The water disappears. Then, after a comfortable 150 m long
straight stretch, the largest section of passage in Gilwern Passage, and a right turn,
another inlet comes out of an aven. The stream from this aven flows north along
Gilwern Passage, in the opposite direction to the Beyond A Choke streamway, marking
the start of the major north-flowing streamway.

Gilwern Passage is then followed, past some protected formations, for a seemingly
endless 750 m. This section starts as a walk in the stream but soon becomes a
more uncomfortable walk over boulders. At the end of this section, it turns sharply left,
while Morgannwg Passage continues up an easy climb ahead. Gilwern Passage then turns sharply
right, and ends at the foot of a more difficult climb, where the water disappears under
a low arch to the left, with the low arch being the main way on.

The water can be followed through the low arch to a
slight enlargement with a dry crawl ahead. This crawl is very short and leads to a
climb up boulders into a (stable) choke where the roof is made from boulders in the
floor of Old Illtydian's Chamber. Once at the top of the climb, the way on is through
two adjoining squeezes (one of which will prove impassable to persons of more
than average build) into another enlargement. The low arch straight ahead is the
way on. The roof now becomes solid and covered in bunches of gypsum. This the
start of Forever Changed, the initial passage of the Galería Garimpeiros
Extensions.

The climb up into Morgannwg Passage quickly reaches a junction. Morgannwg Passage
continues ahead at the junction, but to the left instead reaches another junction.
To the left here is the more difficult climb down into the end of Gilwern Passage,
and a climb up ahead-right leads to the large, but dead end, Old Illtydian's Chamber.

Morgannwg Passage soon gains an inlet stream, at a crystal pool with (mostly sunken) calcite rafts.
The 175 m passage beyond is taped off to protect the rafts and crystal pools, and cavers are
requested not to proceed any further. The first three crystal pools require very difficult traverses,
with it being nearly impossible to avoid dropping mud, dirt, and gypsum into the pool.
The third pool can be partly bypassed using an oxbow, with a blind side passage having some rafts.
A short, dry section then reaches the fourth pool at a corner, which has many small calcite rafts,
and requires a very tricky traverse at high level over the pool. The passage then loses its water,
soon requiring a very awkward, narrow traverse at roof level, followed by a narrow ascent to a choke,
where a squeeze regains the passage. This passes a too-low oxbow on the left and a short side passage on the right,
and ends at a total calcite blockage, with no prospects.

Forever Changed carries the Gilwern Passage streamway but this disappears to
the left when the passage begins to enlarge.

Forever Changed now becomes lower and progress is made by crawling over
large dried mud banks. This only lasts for a short distance and the passage gets
larger again when the stream re-enters from a sump on the left. Here the passage
gets very muddy and the taped path generally follows the stream through knee
deep mud. Fairly soon a high level passage comes in from the left and the whole
passage gets larger again.

Ahead at this point a 1 m tall, gnome-style stalagmite, the Guardian, is seen ahead
under a pure white curtain-stalactite, while a multitude of straws decorate the walls.
After this the roof lowers again and the path leaves the stream to wander between
some 1 m long straws. The path then follows the stream again for a short distance
to a junction where another streamway, carrying a larger stream, enters from a
somewhat smaller passage straight ahead. The combined streams then flow off
to the left, along a lower but wider passage to become the Y Gwter Fawr streamway, the way to Saint Giles Series.

Continuing ahead (upstream) the Hearts Of Olden Glory streamway takes on a
superb, echoey, phreatic style to a sharp right hand bend. Here the phreatic style
continues ahead (the way to Another World), while the stream swings right and the passage takes on a more
rifty style as it continues. A side passage on the right ends after some distance
having passed through a chamber.

At the point where the side passage leads off, the stream passage swings back
to the left. It continues with the rifty style for about 100 m to a choke. Here a high
level passage leads off on the left. This will be mentioned later.

Another World

Continuing ahead at the sharp right hand bend in the Hearts Of Olden Glory
streamway, the start of an area of passages known
as Sons Of The Pioneers, eventually leads after some distance to a crawl. This, in turn, ends at a
short climb up by some slightly muddied stal. At the top of the climb is a chamber with some columns.

An obvious passage leading off to the right from the chamber can be followed
through a low arch to a decorated chamber. The main way on here is straight
ahead, but to the left a passage doubles back, The Green Grovel. This passes by a tall stalagmite
and stalactite, with straws decorating the walls (great care must be taken). The
passage reaches a small drop from where a low crawl on the right can be followed
for 100 m to where it branches. Both branches close down shortly afterwards.

Back at the main way on, the passage starts about a 1 m high but very quickly
opens up into a well decorated chamber, Another World. The main way on from
here is to the left. This large passage crosses over a small stalagmite in a dried up
streambed in the floor, and passes a dead end passage on the right before a small
passage leads off low and to the right. This winds its way to the high level passage
mentioned earlier near the choke at the end of the Hearts Of Olden Glory streamway.
The main way on continues ahead past this small passage.

Indigo Rift

The main way on (from Another World) leads past more formations to a Y-junction. The passage to the
right follows a mature rift to a large cross rift where the passage to the left enters
the left fork from the Y-junction. Following the left fork, a climb up into an aven leads
to a flat-out crawl that will be mentioned later, whilst continuing ahead follows an
almost perfectly circular mud-floored passage. This soon becomes more straight-
walled with a rounded roof. Three avens are passed before a choke is quickly
encountered. The first is to the right, the second a little further on, is in the middle
of the passage, and the third is entered through a narrow rift to the right. Another
aven can be entered via a low crawl to the right.

The three main avens unite in a large chamber with two ways leading off, a low
passage to the left, which leads to the flat-out crawl mentioned earlier, and to the
right is Indigo Rift. Progress along here is made by traversing high up on very
friable ledges coated in a thin layer of slippery black mud. Initially, Indigo Rift
passes over the fourth aven, but further on many other holes can be seen in the
floor. Eventually a large one is reached. This has been bolted to gain access to a
series of small passages that will be mentioned later. Indigo Rift continues after a
climb up over this hole. The going slowly becomes easier after this until, after
some distance, a junction is reached. A flat-out crawl to the left enters a dead-end
enlargement, straight ahead is a small, winding passage with a few side passages,
while to the right leads to a loose choke. Down a small hole to the left before this
choke, leads to a series of small passages containing a dry streamway and a
pitch with an aven up into the already mentioned bolted hole in Indigo Rift. A climb
up into one of these passages provides a difficult way into The Realm of Baron
Von Carno, but is not the usual way in.

The Realm Of Baron Von Carno

This passes very close to both the end of Indigo Rift, and Lost River Passage in
Waterfall Series. Most of the passages in this series are crawls and several loops
are possible. This area is only for the ardent passage-collector!

The main way into this series is to drop down through the floor of Indigo Rift, half
way between its start and the bolted hole, to where a small stream is seen to
enter from a crawling-sized passage. About 15 m along this, some passages to
the right connect with the other route into this series (mentioned above). A further
20 m in the way on is to the right while the stream enters from the left. Another
30 m on, beyond a squeeze, a hole up enters a passage in a cross-rift. To the left
can be followed for 100 m, whilst to the right enters Kebabarama Drama after
100 m (see later).

Continuing at the lower level, 30 m and several junctions later, the passage
reaches a junction at a cairn (present as of 5 April 97) with Fastrack Membership
ahead and an inlet, The Stream Of Running Commentary, to the left.

Fastrack Membership is a tight oxbow so the inlet itself is usually followed. About
130 m along The Stream Of Running Commentary, some holes above enter the
main passage of The Realm Of Baron Von Carno, at the same point as Fastrack
Membership enters from the right. 100 m further on, some passages to the right
enter Kebabarama Drama. A side passage along this section heads off for
400 m trending away from the rest of the cave, and contains a seasonal sump; this
should only be followed after extended periods of dry weather. A further 150 m on, The Stream Of Running
Commentary enters the end of The Realm Of Baron Von Carno. This larger,
decorated passage can be followed for 500 m to where it closes down. Some
200 m along this are the holes down into The Stream Of Running Commentary.

The downstream passage of Y Gwter Fawr continues for a short distance past
some straws and around a few bends to a low, wet crawl. This opens up after a
short distance in a chamber. The way on from here is along another wet crawl
which was once, and sometimes still is, a very muddy and intimidating duck; Brownout on Breadfruit Boulevard. This
is about 30 m long, gradually lowering before becoming slightly higher about half
way along, and is the start of Breadfruit Boulevard (Chapter 1).

Once out of the duck, the passage enlarges to stooping size with mud banks but
this quickly becomes a short crawl. Following this the passage returns to stooping
size with crawls over mud banks and enlarges progressively over 300 m to become
over 10 m wide and 15 m high. At this point, however, the passage chokes at the April Fool Choke. Just
before the choke, an inlet to the right can be followed for 10 m to a fork. To the right
can be followed further than to the left but neither are longer than 30 m.

The route through the April Fool Choke begins at the top on the right and climbs steeply to a
loose but level passage. This is Saint Giles Passage at the start of Saint Giles
Series. This enlarges over 20 m to become 7 m high and 15 m wide. Some 30 m
ahead, a side passage to the right is the start of the Lamb And Flag Passages.
Beyond the passage descends a steep and very loose slope (take care) to regain
the stream. The passage at this point is about 10 m square with large mud banks
although these quickly give way to boulders. The passage then becomes
progressively higher (perhaps as much as 20 m high) with several boulder obstacles.

At one point, a large boulder spans the passage giving a choice of routes, over or
under. Immediately on the other side of this, two holes to the right enter Clerical Error.
This passage is not to be followed to protect its floor of dried crystal pools, which
can be seen from its start.Ahead,
the lofty passage continues to a rise up boulders. At the top, the passage is more
square-shaped. About 20 m along here, the taped route splits. To the left, a laddered
climb up a stal bank is the route into the Dyar Straits Streamway, while a further 20 m
ahead leads to another split in the route. To the right here is The Wiggly Business,
while to the left, the passage becomes much lower and arched. This quickly opens
out to its former size, passing a crystal pool containing some cave pearls, and
continues to enlarge.

Ahead the passage contains some deep pools of water and mud (these are easily
avoided by narrow ledges to the left, just above the water) and ends after 200 m in the
well decorated Passion Fruit Chamber. Here the way on fills with mud with the only
notable side passage being 40 m before the end, a narrow rift 50 m long.

The Wiggly Business begins as a low arched passage and continues for 350 m as
sections of passage, similarly sized, intersected by many squeezes and small chokes.
The last of these chokes breaks into 130 m of larger passage, a possible continuation
of Saint Giles Passage from Passion Fruit Chamber, which is well decorated with
crystal pools and other calcite formations.

Lamb And Flag Passages

The initial section of the Lamb And Flag Passages is 3 m square but quickly becomes a
tall rift. Two routes can then be followed, along the floor or 3 m above. The lower of
these two options is the start of Lamb Passage, which contains a stream, whilst the upper is Flag Passage.
These quickly become separate but follow a similar path. At a point about 100 m along
either, they rejoin, with Lamb Passage entering from below through a choke in the floor
of Flag Passage.

Flag Passage then continues past a crossroads with side passages
on either side, the one to the right probably being the way to Blue Crocodile Passage (to be confirmed).
At the next junction it continues ahead-left to reach a major
junction of routes. To the left passes through a choke after 60 m, and ends in silt
fill after another 50 m. To the right leads to a dig at roof level after 15 m,
to enter Pixie Meadows. Beyond the dig, a cairn marks
the location of a calcited climb on the right into Keyhole, while a crawl ahead reaches
the head of a 4.5 m pitch, rigged from 2 bolts above the pitch. At the bottom, a larger passage continuing in the same direction
as before reaches a junction after 45 m. The passage to the right soon becomes a
canal with deep water, which finally sumps after a 4 metre duck with very little airspace.
The passage to the left ends after 30 m in a small stream passage.

The calcited climb is about 6 m tall, and reaches a phreatic passage. After 20 m,
this reaches a junction with Keyhole. Downstream Keyhole leads to the right for 50 m
to a choked rift. Upstream Keyhole leads to the left for 25 m, passing low digs on
either side, to end at a tight rift.

The route to Blue Crocodile Passage passes through a squeeze into Blue Crocodile Passage.
50 m further on, at a choke, a hole in the floor descends a rift to reach an aven.
A squeeze leads into a side chamber, where a descent through rocks in the floor reaches a
way back into Saint Giles Passage, near the April Fool Choke.

Dyar Straits Streamway

At the top of the ladder climb, an oval tube 1 m high reaches a small step down after 5 m. The
way on from here is to continue in the same direction, feet first, along a much smaller
tube to reach a drop down. This is aided by a fixed handline and is the top of a 7 m
descent down a narrow rift to reach the Dyar Straits stream, which is also known as the Sanitizer Streamway. This rift is very awkward on the return
and should not be attempted by tired or inexperienced cavers. The stream can be
followed upstream for 10 m to reach a choke in the floor of Saint Giles Passage, the
source of the stream. Downstream the stream descends steeply, but without any
cascades, to end after 300 m of narrow, zig-zagging streamway, in a very low, silted
sump. This is the present limit of the downstream cave. From here, the water
flows west for 400 m to resurge in a small cave under a limekiln beside Cwm Dyar
(referred to as Clydach South Resurgences No 1 in The Caves of Clydach - Tony Oldham).

The passage is decorated throughout its length with both new and very old formations
(though none are particularly memorable) and has two main side passages, both of
which are to the right. The second of these, The Land Of Mr Ugg, which is about 200 m along the streamway, reaches
a tight and awkward rift passage which has not been pushed to a conclusion!

5. The East and the "Round Trip" route

This section contains the description of the "Round Trip", followed by the
descriptions of some of the major side passages and minor series encountered en-route,
followed by the series leading into the southeast area and finally the "Long Round Trip".

Tea Junction to Lamb and Fox Chamber

To the left at Tea Junction is White Arch Passage. This boulder strewn passage is
the obvious upstream end of the Beyond A Choke streamway although it is not
called so. After about 45 m, Back Passage (the first significant side passage, just after
a blind alcove that can be mistaken for a side passage) leads off up a
small slope to the right, and is the way into The Score.
Back Passage begins as a rift, and soon lowers to a bedding crawl.
Shortly after Back Passage is a larger side passage to the right, which begins as a fairly wide bedding plane crawl.
This passes through a narrow section and ends after 70 m with a visual connection to Crystal Cruncher's oxbow in The Score, just after a squeeze.

White Arch Passage continues upstream to reach a hairpin bend to the right, and immediately afterwards, Carpet Crawl enters from up a
slope to the left (the left-most of the two passages at the top of the slope). Shortly after this, a shattered
climb down is reached.

The passage continues for another 100 m of large streamway, to where the next significant side passage is seen as a 2 m high opening on
the right on the outside edge of a left bend, called Flood Overflow Passage. This leads to a very muddy, tight,
streamway known as Typically Tropical. This is about 100 m long in the upstream direction (to the left) and
passes under Raiders Passage, and is some 50 m long and rather lower
downstream (to the right). Both directions end in sumps, with the downstream sump's water
quickly emerging from a sump tucked under the wall in White Arch Passage.

Shortly after passing the side passage, White Arch Passage enters a passage-chamber after passing
through an impressive arch (although the author fails to understand the origin of the
adjective white!). The passage then turns left and continues for a further 100 m to
where a large boulder choke is reached. A way can be found through at the top
right hand side of the choke into the lower end of the enormous Lamb and Fox
Chamber, with its house-sized boulders.

Lamb and Fox Chamber

Lamb and Fox Chamber has two dead end, low level, side passages next to the way out
of the choke, one to the right, and one some distance away to the left. The passage to the right is about 100 m of crawl. The passage to the left,
Humpty Dumpty Passage, can be followed through a small choke to a pitch (10 m) and a traverse to an aven (5 m) each leading
to short sections of stream passage. Beware of friable rock around the pitches in Humpty Dumpty passage,
falls have occurred here; a handline or ladder is essential, especially for the bottom 3 m of the pitch.
High on the left in the chamber is a cascading inlet, even higher above which a rift
passage can be followed past a large bedding plane to the right to a choke. Just
before the choke, a low passage to the left can be followed to a series of climbs
down, leading to a passage containing a stream which can be followed until it emerges
in the north wall of Lamb and Fox Chamber where the stream becomes the cascading inlet.
The bedding plane also has a dead-end inlet, and an oxbow leading back into Lamb and Fox Chamber.

The cascading inlet has been used as a drinking water source, though the water has not been
tested for purity. A water collection bucket is often left at the bottom of the cascade (to the
left as you enter the chamber) for this purpose, but this is not an official aid, and cavers
should bring a bottle for collecting water if needed.

The way on from Lamb and Fox Chamber is up the boulders and over to the far right hand side of the chamber,
at the top of a climb up a cairn, and is a high level rift perched on a ledge on the right
hand wall of the chamber.

Indiana Highway

The high level rift (at the top of the cairn) from Lamb and Fox Chamber
begins as a stooping height passage, but soon gets higher before a large bedding plane
crosses in the floor below, with the way on continuing on the other side.
To the right in the bedding plane is the start of Raiders Passage. To the left in the bedding plane,
a climb down enters a chamber with a large 25 cm long fossil in the roof on the left, and a flat out
crawl on the far side on the left, which leads back into Lamb and Fox Chamber. The crawl is 40 m long,
and is inhabited by bats, so should not be entered. A very small passage to its right, Guano Crawl, which is also
important for bats so should not be entered, connects with
the bottom of the traverse further down Indiana Highway after over 50 m.

The usual way on is either to traverse
over the bedding plane, or to drop down into it then climb back up into the continuing rift at the
other side.

The continuing rift - Indiana Highway - is easy at first, a stooping-standing passage with a dried mud
floor. After a short distance, the rift from the side passage in Raiders Passage
(described later) is seen on the right. The way on continues past this, down and up
some slopes, before the floor drops away, and the main traverse begins. This continues
for a considerable distance. At one point, the normal walking ledges disappear, and a crawl
to the left bypasses an awkward corner. Immediately after this, a rope is reached. This is a safety
line across a 20 m deep shaft, Lost Crusade, in the floor. The shaft is not the usual way on, but may
be descended using a 40 m rope, rigged from spits at the bottom of the Indiana Highway rift with backup to traverse P-hangers.
At the bottom of the shaft, a short passage, Destiny, leads to a further 8 m pitch and then ends in a
dangerously loose area. The 8 m pitch has a squeeze-sized pitch head, and is
perhaps best rigged with a ladder from spits above the pitch head.

Indiana Highway continues over the shaft to a breakdown chamber.
Two passages lead off; to the right is the Canyon (described
later), while straight ahead a climb up boulders leads to crawls round to the left
on exposed ledges either side of a canyon in the floor. This in turn leads to a
junction between Megadrive (ahead and to the right) and Megadrive North (ahead
and to the left), with Megadrive being the way on for the Round Trip and the southeast area of the cave.

Megadrive to Saint David's Hall

From the Megadrive and Megadrive North junction, turning right heads along a low,
impressively wide bedding passage, the Megadrive. This quickly becomes much
higher. After 100 m, the larger Siambre Ddu Passage doubles back on the left (note: it is
easy to accidentally follow this passage on the way out if not doing the "Round
Trip"). This can be followed for 150 m to a large choke with two avens (one part
way into the choke).

The Megadrive soon becomes more diamond-shaped and continues for some
distance getting higher and wider (in some places it is large enough to hold three
buses!), until the passage shrinks in size at an obvious corner. Here the passage
takes a sharp left turn before continuing as a much smaller passage, The Nunnery.
This starts as a low, very draughty crawl but soon opens up to become more
square-shaped. After a short distance, Going Square leads off to the right at Windy Junction and The
Nunnery takes on a shape more reminiscent of a mine.

The next passage along The Nunnery is Perseverance II on the right. This is the
usual way on. The Nunnery continues past this junction however, and another
passage on the right (the original flat-out crawl route into Perseverance I), until an echoing chamber, The Chapel,
is reached beyond a dangerous looking choke. Here the passage continues after
a scramble down to the left but terminates after about 5 m in another loose choke
which is very close to the surface (this choke was dug to construct a second entrance,
but this was then filled in and sealed, and must not be used - the construction of entrances
here is prohibited by the landowner and the cave management group).

Perseverance II is a crawl for the first 70 m, becoming a larger
square passage just before some calcite formations. The main way on is to continue along the larger passage, but behind the formations on the right, the
tight Hoo Hoo Crawl leads, after much squeezing and tight crawling to Going
Square. Continuing along Perseverance II, the square
shape soon turns right and gives way to a round, sandy floored, passage. Shortly afterwards, Perseverance I
(the way to the Long Round Trip and the southeast area of the cave) leads off to the right.The sandy passage of Perseverance II continues ahead (the way on for the Round Trip) until the floor suddenly falls into The Arms
Park from the 8 m high Balcony Pitch (a fixed ladder has been installed).

Two passages lead off from the bottom of the pitch, while a 7 m pitch up on the far side
(originally maypoled but a cord was in place for rigging a pullthrough rope in 2017) leads to Erection Series. Erection Series is a 100 m
long passage with its terminal choke that is very close to the surface. An oxbow on its left side has a pit
requiring a 6 m pitch down, a 10 m pitch up, and a climb down to complete the oxbow.
In Arms Park, the passage ahead-right (as seen from the head of Balcony Pitch) at floor level leads for 100 m
to a point where a way on is through a bedding to the right. This ends after 50 m in
an area of breakdown near The Chapel and under Erection Series.

The way on from The Arms Park is the left hand passage (as seen from the head of Balcony Pitch), The Players' Tunnel. Starting low down, this
quickly leads into an enlargement, with the way on down a hole through boulders to
the left. Continuing along a large boulder-strewn passage for some distance leads to
the enormous Saint David's Hall beyond an easily passed boulder ruckle. This chamber
contains innumerable numbers of boulders on the floor but has a perfectly flat roof.

Saint David's Hall to the Beyond A Choke Streamway (the "Round Trip Connection")

When using this section to access Life on Mars or Crystal Maze via the Beyond A Choke Streamway, follow this section in reverse.

From Saint David's Hall, there are two ways on, and both may be used for
the Round Trip. The original and usual route is Squirrel Rifts, while Agent Blorenge II
is an alternative option.

At the far end of Saint David's Hall, a low passage called Game Over (originally named Swallow Series) leads off, for about 100 m.
At its start, a route on the right leads down through the choke in the floor of the
chamber into the end of Agent Blorenge II. This starts impressively wide, and carries
a significant stream under the boulders. It can be followed for 250 m,
through some surprisingly large sections of passage. After passing some oxbows, the
roof lowers to stooping height, and the passage passes under an aven into a blind rift,
before ending at a sump.
Just before the passage lowers to stooping height, a tricky climb up to a
ledge on the left enters a steeply ascending, narrow rift,
leading up to a junction with the Squirrel Rifts main route. The main way on is
to the right, which quickly reaches the chamber where the way to the "Round Trip
Connection" is to the left, and Wooden Spoon Passage is to the right.

From Saint David's Hall, a short crawl high up amongst the boulders
on the left gains the main way on, through the complex and misleading Squirrel Rifts.
All of the significant side passages in this area are either oxbows
or enter Upper Rift & beyond (see that section for details),
with the first hole on the left leading directly into Agent Blorenge III.

After a right turn about 25 m along the passage, the way on follows the largest
passage until it reaches a junction with a large cross rift after about 250 m, where
there is both a high and a low level continuing ahead. At
many points along this section of passage, the route turns sharp corners, often giving the impression
that the passage is heading in the 'wrong' direction. At the last right turn before the cross rift, in a wider section, a hole ahead drops into
Upper Rift & beyond, and is the preferred route into that area. To the right in the cross rift reaches an awkward hole down which
connects with the end of Game Over. The way on from the junction
is into the cross rift to the left. Almost immediately, this rift continues ahead as the pitch route into Upper Rift,
while the main way on is down a sloping hole to the right (or a second hole immediately
after it).

From here on the way on becomes more obvious, quickly passing through a keyhole-shaped
section. A right turn followed by a climb up boulders leads to more keyhole-shaped passage,
with many short, dead-end side passages. Only two side passages are of any size, the first heading
to the right and containing some chocked boulders at its start. The second significant side passage, Sparrow,
is down an obvious hole to the left just after a climb down. The hole to Sparrow descends a climb and a funnel of rocks, before leading through two eyeholes where a stream can be heard in a blind side rift, to reach a junction. To the left closes down while to the right soon reaches a junction with a stream passage to the left and a dry passage ahead. The stream passage soon passes through a wider section to become a narrow rift which soon ends after an awkward climb, while the dry passage passes through an enlargement where a crawl diagonally opposite soon reaches Sparrow's terminal chamber with a too-tight rift on the opposite wall, and a bat skeleton on the mud floor.

Back in Squirrel Rifts, after 150 m since the junction with Upper Rift, in a section with old stal decorations in the roof,
another short side passage leads off to the left while the main way turns to the right, then back to the
left in a funnel of boulders. Shortly afterwards, some rifts on the left lead into the
"Round Trip Connection" and Haggis Basher Number One, but are not the usual route.
The first ascends a climb before turning right in an enlargement and passing down and up climbs to reach the pitch down to Haggis Basher Number One.
The second reaches an enlargement and passes through a squeeze to the left, eventually passing a side passage reaching the Round Trip Connection on the right, before connecting to the first route just before the pitch.

The main passage finally terminates after a further 25 m in a chamber with the large
Wooden Spoon Passage to the right and a smaller one to the left (the usual way to the "Round Trip Connection"). Two corners before this
chamber, a steeply descending rift on the right leads to Agent Blorenge II, and the alternative
route from Saint David's Hall. (When heading upstream in Agent Blorenge II, the way through the choke
into Saint David's Hall starts on the right.)

Back at the chamber in Squirrel Rifts, the main way on is to the left. After 35 m, it turns right and develops a deep trench in the floor, which is the usual way on.
On the way to the trench, the passage passes an alternative hole down on the right which connects with the bottom of the first Round Trip Connection climb, as well as an oxbow on the right, while to the left at the corner connects with the alternative route from Squirrel Rifts into Haggis Basher Number One, where the way to its pitch is to the right.
At the bottom of the trench, a passage doubles back beneath the way in, to another hole down, where continuing ahead above the hole only leads back up to the passage above the first climb. On the left above this second hole,
a low alcove contains one of the routes into Life On Mars,
while dropping down the hole reaches a narrow rift doubling back again towards the same
direction as the passage above had been heading (the "Round Trip Connection").
The rift becomes crawling height and narrows to pass through a squeeze into Haggis Basher Number One,
a relatively large passage which heads in both directions and carries a small stream.
The main way on is downstream to the right, and the alternative route mentioned earlier enters from an aven above the junction.

When following the Long Round Trip, follow the next paragraph in reverse.

To the left in Haggis Basher Number One leads past good formations to a choke. The choke can be passed by way of a hole
on the left, most of the way up it. Ducking under a large boulder then gains Haggis
Basher Number Two. This can be followed for 60m, past some formations and
a short inlet, to a chamber and choke. Immediately to the left in the chamber, a low
crawl is the connection to Interesting Times, and the Long Round Trip.

To the right in Haggis Basher Number One, the passage remains large. After 20 m, a
ramp on the left leads to Life On Mars. About 40 m further
on along Haggis Basher Number One, just after a boulder pile, the large Sump Inlet passage leads off on the right but this soon sumps (the
other end of the Agent Blorenge II sump), with a 50 m long side passage to the
right passing over an airbell in the sump. The main way on continues downstream, as
Far Agent Blorenge, a big gravel-floored streamway. It passes several oxbows and the 150 m long
gypsum decorated Crystal Mole passage to the right, to a point where the water disappears
down a rift to the right. The way on is a crawl ahead into a chamber, where the stream
enters from a small rift to the right. From the chamber there is also the downstream passage of Agent Blorenge to the right, and a crawl ahead
over sand. If negotiating the Round Trip then either route can be followed.
The stream route, however, is faster and less exhausting, and reconnects with the
other route after 80 m at a small cascade, just after a traversing section,
where the way on is downstream.At this point, a climb up into a rift on the left instead (the end of the alternative route), and
a traverse over a hole reaches an inlet, where the crawl into Crystal Maze is on the right,
opposite the inlet.

Around 30 m along the alternative crawl ("Chocolate Blorenge"), a smaller passage
ahead-right is the way on, while the larger passage ahead closes down.
30 m further on, the smaller passage enlarges to standing height. A
climb overhead to the right leads into 40 m of passage which ends above the stream route, while the main route continues ahead below.
Immediately after this, an inlet enters from the right. Opposite the inlet, a crawl to
the left leads to Crystal Maze, POB Passage and The Swim. Continuing ahead past the inlet,
a junction is reached almost immediately. To the left, a stooping-sized passage can be followed for over 20 m, while
ahead, the main way on leads along a traverse over a hole, which reaches a climb down to the junction with the stream route at a cascade.

From the junction of the routes at the cascade, the way on is downstream, but almost
immediately becomes an extremely tight rift. The tight rift can be bypassed by an eyehole and climb down to the
left, where the ongoing streamway immediately enters The Sewer, a 30 m long, 1.5 m high passage half full of
water.

Beyond this, the way on leads along a traverse that ends at an awkward climb
that looks easy from the top. A 10m doubled handline is advised, looped over a small
spike of rock 3 m off the floor at the first available route down the climb (this
was rigged with an unofficial handline as of September 2017).
Almost immediately afterwards is the Second Sewer. This is shorter than the first but
begins with a duck where it is possible to keep your head dry. A difficult chimney
up the tight rift immediately above the duck reaches a higher level bypass. Downstream
from here leads down a series of small cascades and exposed climbs, characteristic of
this end of Agent Blorenge, to the Beyond A Choke streamway (see that section for details) at The Confluence. Upstream from here leads
to Tea Junction, and the end of the Round Trip.

Raiders Passage

Raiders Passage has only two significant side passages, the first almost
immediately on the left and the second, a flat-out crawl also on the left, not too far
past the first. These actually join and two rift passages lead off. A narrow rift on the
left leads past some enormous deposits of bat guano to Indiana Highway, while
that to the right enlarges and continues for some distance. This is a large passage
with the rift winding in the roof but comes to a dead end. Back around 10 m is a
long flat-out crawl over sand to the right. This leads to two chambers, the upper one
of which appears to connect with a rift in Canyon West, but the connection is too narrow.

The main Raiders Passage is, however, straight ahead into a rift in the floor at the
start of the second side passage mentioned above. Raiders Passage, like the
series past Big Bang Pitch, contains many fossil shark spines up to 25 cm long.
The passage immediately obtains a solid roof and enlarges (up to 3 m high and
2 m wide). After about 75 m of phreatic style, Raiders Passage takes a sharp left
bend in a larger section of passage. Immediately after this corner, a fossil spine about 25 cm
long (the largest in the passage) can be seen on the wall to the right.
For about 400 m from here, the passage becomes more shattered, necessitating a few
climbs and stoops, with occasional short oxbows.

The passage displays a distinctive orange and white colouration on either side and has an
unconformity in the roof. Many fossil pectoral and dorsal spines, large piles of bat guano (up to
3 m long, 1 m wide and 0.5 m high!) and gypsum "cornflakes" can be seen along
here before the passage splits in two. To the right a low passage (the usual way on) becomes flat-out
before entering the other passage, while, to the left, the larger passage continues up
a small climb. When the two passages join, the phreatic style again takes over and
the passage continues for a further 400 m until it joins a larger and higher passage.
To the left closes down very quickly, while to the right leads along an almost
perfectly straight rift, past a short side passage, to a hairpin bend to the left.

On the bend, a large fossil can be seen passing through a flake of rock on the left.
From here, the passage becomes noticeably phreatic and passes many short
oxbows and natural rock bridges until it appears to fill up with mud. This can be
crawled over to access another section of large phreatic passage with many small
oxbows to where it also appears to close down. Here a small crawl ahead leads
into a small chamber. To the left leads to a dead end, while to the right leads to a
dig, the end of Raiders Passage.

The Canyon Passages

After the start of the Canyon a smaller rift passage quickly leads off on the left. This
is Canyon East. Meanwhile the larger passage leads into a chamber. To the right
here, is the other end of the loop from Megadrive North, to the left leads to a side
passage in Canyon East a few metres after its start, while straight ahead and left
leads to a series of three oxbows (with a large pile of guano) with three passages leading off. Two of these
are dead end rifts (one of which is assumed to connect with the end of the side
passage in Raiders Passage), and one of which is the more rounded Canyon
West. The two Canyon passages join after 350 m (along either passage) and
continue as a tall, somewhat keyhole shaped, passage. 100 m further on, Big
Mole Passage leads off high on the left. The Canyon continues for a considerable
distance but a few hundred metres before it ends, the 250 m long Tractor Tracks
Passage leads off to the left (south) in a complex area of passages at different levels.

Megadrive North and Underworld Series

Megadrive North begins wide with a deep rift in the floor and can be followed for
200 m, initially through a shattered section, to a choke. For most of its length, the
rift in the floor meanders through 15 m wide beddings to the right, while
occasionally crossing the taped path through the main part of the passage.
One of the early undercuts on the right contains the downstream end of Black Beetle
(mentioned later), while a hole on the left enters a series of oxbows formed in the
undercuts. About 100 m along Megadrive North, just before a 15 m waterfall in the middle of the
passage, a triangular shaped passage (point upwards) can be seen to the left.
This can be followed through a zig-zagging section, beginning with a sharp corner
to the left, to reach the Canyon.

The choke at the end of Megadrive North is in a chamber with several other routes
leading off. To the right, a passage beginning in an undercut can be followed to a
short oxbow, with the route to the right a rift and the route to the left a crawl at head
height. Where these two routes join, two routes again lead off. To the right, an
obvious rift passage ends quickly while a route hidden behind boulders to the left
drops down into Anastomosis passage. To the right here ends quickly, to the left
reaches a squeeze onto a climb into the chamber at the start of Blue Eyes Cryin'
and Faded Love (both mentioned later), while ahead, a small stream passage can
be followed upstream for 50 m, becoming increasingly small, to reach gravel fill in
a turning space.

At the point of entry to the chamber at the end of Megadrive North, a trench passes
from the centre of the passage to the left. The climb down into this is loose so
should not be used. About 10 m beyond this, however, a second section of trench
can be descended easily where a bedding plane at floor level (heading to the left
when facing the choke at the end of Megadrive North) can be followed to a small
enlargement. To the right, the bedding continues to enter a larger passage. To the
right here, a crawl re-enters the trench, while to the left, 20 m of walking-sized
passage reaches a choke. The edge of this can be followed to the left for 10 m,
while a climb above leads into Fear Of Flying, 75 m of passage with several little climbs.

At the first enlargement in the bedding plane, three holes known as Lemming Pot drop down in the floor
(the one directly ahead should be the easiest to descend, having a boulder pile
beneath it) into a large chamber. This is the start of Underworld Passage and
Underworld Series. To the right here, the large passage continues, passing a
bedding to the left almost immediately, and a large echoing aven slightly further on,
to a point where the passage ends at a large crater and boulder choke, 100 m from
its initial chamber. Just before the crater are two blind pots and a small passage on the right which chokes
after 20 m. 10 m before these blind pots, a 22 m pitch drops down to the right (backup to
a solid boulder, there is a bolt rebelay 3 m down on the near side of the pitch).
This enters Underworld I, which may be incorrectly marked as Under Underworld on
some surveys. At the bottom, the stream that sprays (in most
conditions) down the pitch flows North-West through a very muddy grovel, to reach
a choke after 20 m. About 5 m before the end, the masochistic can follow a very
low and exceedingly muddy passage for 50 m. Half way along on the left is a
small chamber with a blind 10 m aven.

Heading in the other direction along Underworld I, 100 m of wide,
crawling/stooping passage enters a decorated chamber. To the left, the passage
shrinks slightly to reach an inlet choke, just beyond a calcite floor. Ahead, a
smaller decorated passage reaches an impenetrable sump after 35 m, just beyond
a small stal grill, while to the right, a hole down enters a torturous 150 m long
streamway, with several old formations, to reach a totally silted sump. Water in this
passage would almost certainly back up in flood.

The bedding to the left in Underworld Passage reaches a crater, which can be
descended in stages to reach a well-washed passage. This leads to a 5 m climb
down to a stream (the same one seen in the early portion of Underworld Passage,
Blue Eyes Cryin' and Anastomosis Passage), Underworld II. Almost immediately, two 5 m pitches
are met in quick succession. The first having bolt holes above the pitch and the
second probably having the same (although none were found on a reconnaissance
trip). At the bottom, 30 m of very tight streamway reaches a too tight section.

In the chamber at the start of Underworld Passage, a route can be forced (with care)
through boulders to the left to reach a blind undercut. The stream below issues from Blue Eyes Cryin', although
there is no physical link. Ahead in the chamber, holes through boulders in the floor
reach the stream again in another blind undercut. Above these holes, a short and narrow rift
with phreatic shelves can be followed for 20 m to a chamber. To the right, a short section of
passage reaches the climb up to the squeeze into Anastomosis Passage. Ahead is
a continuation of the narrow rift and down a hole in the floor, just to the left of the
previously mentioned passage, is Blue Eyes Cryin'. This consists of 50 m of stooping
height, but wide, passage beginning with a trench in the floor containing a stream and
ending in a choke. The continuation of the narrow rift, Faded Love, gradually enlarges over 50 m
before breaking into a short section of larger passage terminating in a choke. The
choke at the end of Blue Eyes Cryin' is in the floor at the start of this section of passage,
suggesting that these two are in fact one and the same passage.

Black Beetle

Black Beetle has two access points, but is generally easiest to navigate when accessed from Siambre Ddu Passage.
A short distance before the end of Siambre Ddu Passage are two low beddings to the right. These are
sometimes taped off to prevent casual visitors, but may still be accessed with care to avoid damage to
the mud floor. The bedding further from the choke is easiest, and is soon joined by the other. The
combined passage follows a narrow rift in the floor before entering a wider section. This has a large
choke to the left (this can be ascended for a long way, but is not stable, and visits are not advised),
and several too-tight holes around the perimeter. A slot in the floor reaches Black Beetle, with its
fairly significant streamway.

The slot is quite tight, and lands on top of a boulder pile which should be treated with care. An
extra step down reaches the downstream passage, while a hole to the side (to the right when approaching
the slot from Siambre Ddu Passage) is the upstream passage. The upstream passage starts small and requires
crawling in the stream in several places. It reaches a choke after 40 m.

In the downstream passage, a small inlet to the right reaches a muddy chamber after 10 m. All ways off are
choked, or have too-tight connections back up to the bedding in Siambre Ddu Passage. 10 m further downstream,
a roof tube reaches a choke after 15 m. The downstream passage continues for another 100 m with
some rock obstacles, before the stream flows out under the right wall. Following the stream back into
a larger passage, to the left is an inlet which reaches a choke after 25 m. To the right soon loses the stream,
and a dry passage to the left here enters the side of an undercut in Megadrive North.

Going Square

Going Square begins walking/stooping height and reaches a crawl after 60 m.
This enters a chamber with short side passages to the left and right, and one
heading back under the crawl. The way on is through another crawl ahead-left.
About 15 m ahead, a hole down to the right enters an oxbow that lowers to
a crawl. This will be mentioned later. To the left, a passage behind rocks leads
through a very tight section (Hoo Hoo Crawl) into Perseverance II. Continuing ahead,
after 30 m, a short slope down reaches a junction where a squeeze to the left enters
the small passage from the side passages in Perseverance I, and ahead is the way to
the connection with Fault Chambers. To the right is the continuation of Going Square.

About 30 m further on is another junction. To the left is a short side passage
while Going Square continues to the right. Ducking under a rock arch, an enlargement
is reached where a crawl to the right is the oxbow mentioned earlier. Turning left
here, the passage decreases in size to become stooping/crawling height. Ahead, a
crawl in the floor to the right ends in shale fill after 40 m. The way on passes a
short side passage to the right and after about another 50 m enters a chamber. There
are many side passages leading off the chamber, none of which are longer than about
20 m. This complex area is over the middle portion of the Squirrel Rifts.

The way to the connection with Fault Chambers reaches a junction after 40 m.
Clambering into the rift ahead, an awkward climb down in the floor enters Rift
Chamber in Fault Chambers, ducking out from under the wall. This climb has few
handholds or footholds near the top and a very tricky landing. A 10 m handline may
prove useful on the return, although finding a secure belay point may prove very
difficult. To the left at the junction, a narrow passage becomes a traverse before
the floor drops 10 m into a pitch. This can be more easily accessed from a side passage
in Sugar Cube Chamber in Perseverance I. Either route drops 10 m to the floor, where a
further awkward climb down reaches a series of small, very muddy passages and a slippery
traverse.

To the right at the junction in Going Square, the main way on is Fault Rifts.
This begins as crawls separated by short standing sections, one of which has a
short dead-end passage to the left. After several standing sections, one has a
natural rock bridge to the left. Continuing through eyeholes ahead, the passage
branches several times, each route ending after less than 20 m. The way on is
to climb onto the rock bridge (this may be more easily reached by crawling under
it and then climbing up the other side). The way on is to traverse to the left
into an eyehole, running parallel to the way in.

Once through the eyehole, a climb ahead reaches a junction. Ahead-right is the awkward climb up from Rift
Chamber, while back to the right is a further junction. To the right, a crawl
under a choke reaches a clamber down to the head of an awesome pitch, where water
sprays in from 10 m above and lands over 20 m below. The pitch lies almost directly
above the small streamway in Tube Surprise. To the left at the junction, a chamber has
a short side passage to the right and a crawl over a slab ahead. The crawl reaches
a junction with a rift where to the left, a short passage has some short side
passages. Above at the junction, a very tight ascent in a rift for 5 m reaches
Headache. This enlarges and ends after less than 50 m. Passages to the right along
here enter a parallel passage where to the right enters the other side of the pitch
mentioned earlier, about the same distance off the floor, and to the left reaches a
30 m pitch, this time above the first inlet in Upper Rift.

Upper Rift & Beyond

From Squirrel Rifts, Upper Rift's pitch route can be followed through three tight squeezes to a 10 m pitch.
The bottom is more easily reached by taking the preferred route, on the wide right bend in
Squirrel rifts just before the junction with Upper Rift's pitch route.
The preferred route starts as a tight hole down (very difficult to ascend, and quite committing), quickly reaching a sandy junction with a wider passage.
To the right is Downstream passage, which chokes after 35 m, with Ben's Link entering up on the left after 10 m.
To the left is Upstream Passage (not to be confused with the identically named
passage in the northern part of the system) which soon reaches a junction with the way on to the right, and the sandy Tube (that is its name!) on the left.
Upstream Passage soon offers a choice of a flat-out crawl in the stream or a traverse above.
Eventually, it passes through a squeeze on a corner at roof level into Upper Rift. To the left, the route leads over
a traverse to end too tight. To the right, the rift descends a climb, and passes Ben's Link on the right,
to end at the foot of the 10 m pitch, where an inlet enters.

Tube begins as the last sandy slope on the left, and takes the left branch when it immediately splits above the slope.
The passage can be followed through some small sections to where it enters a walking height pasage, where
the way on is to the right, followed by a left at the next junction.
Near the end of the passage, a hole on the right enters Tube Surprise. This
passes several short side passages as it winds its way
for 75 m to a junction with a passage to the right containing a small streamway.
Continuing ahead reaches a choke after 40 m. A route through the choke enters a larger
passage, Agent Blorenge III.

Unlike the other Agent Blorenges, Agent Blorenge III does not contain a stream. It can
be followed for about 30 m to a rift on the left which, after 20 m, enters the Squirrel
Rifts main route before the initial right turn.

Wooden Spoon Passage

Beginning at the chamber in Squirrel Rifts, the 300 m long Wooden Spoon Passage starts walking sized to the right, and passes down and up
rocky slopes before lowering to crawling size with some layered mud banks, passing a side passage to the left.
A lowering passage to the left is the start of a tight double oxbow, while the main route continues to the right,
becoming an awkward rift passing over some inconveniently placed stal. The double oxbow rejoins as a larger passage
down a step to the left, where there is also a short side passage down a crawling-sized hole in the floor.
The main passage continues until it appears to end, with a low crawl continuing over a mudbank to the right.
The low crawl splits in two, with both branches ending in a series of digs.

Life On Mars

In the alcove above the Round Trip Connection, a narrow rift to the left leads via narrow climbs up and down, to end after 15 m.
Shortly before the end, a 4 m climb overhead gains a higher level continuing in the same direction.
After 10 m, it drops down a climb into a wide rift, the main passage of Squirrel Rifts II.
A side passage to the left leads to a window over the junction of Haggis Basher Number One and the
Round Trip Connection. Just a few metres ahead in the wide rift, a side passage to the right is the
alternative way in from Haggis Basher Number One, while the main passage continues ahead above some wedged rocks.

Alternatively, a climb up the ramp from Haggis Basher Number One leads to a crawl on the left after 10 m.
The crawl quickly leads to a traverse along a rift (the same rift is seen from the bottom in the initial Squirrel Rifts II side passage).
After 20 m, the traverse swings right and gains a solid floor. Almost immediately, a passage to the left reaches a window
looking over the Haggis Basher Number One ramp, while ahead enters a larger passage. To the left is the alternative way in from
the Round Trip Connection, while to the right is the main passage of Squirrel Rifts II, above some wedged rocks.

The main passage of Squirrel Rifts II starts as a very small crawl, which is a little larger than it first appears.
After 20 m, it briefly becomes a larger passage, with the main way on continuing ahead.
Where it enlarges, a passage on the right is the initial side passage of Squirrel Rifts II.
The initial side passage of Squirrel Rifts II has a side passage to the right, which passes through a squeeze (beneath the traverse in the alternative way in
from Haggis Basher Number One) to end at a view over the Haggis Basher Number One ramp.
Continuing ahead along the initial side passage of Squirrel Rifts II passes through a squeeze to reach a junction,
where to the left degenerates after 25 m, and ahead passes through several squeezes before it also degenerates after 60 m.

The main way on through Squirrel Rifts II continues ahead at the junction, soon becoming a short crawl, and passing a small side passage
on the left (which may not be noticed). It passes diagonally through an enlargement before entering a standing-height rift to continue to the right.
Soon afterwards is another short side passage on the left. The continuing passage then reaches a T-junction,
some 75 m after the initial side passage, with the main way on being to the right.

To the left, however, a side passage can be followed for over 100 m, starting with a large chamber
(with the floor forming the choke between Haggis Basher Numbers One and Two).
A climb up the stal on the far side of the chamber reaches a well decorated grotto with elaborate anthodites,
and large stalagmites. At the far end, a very awkward squeeze down through the calcite floor reaches a
continuation of the grotto. The squeeze is not tight, but turning the corner may prove impossible for tall cavers.
The continuation reaches a 5 m pitch down, rigged from stalagmites, with an awkwardly narrow section at the top. At the bottom, a side passage ahead-left is 50 m long,
while the way on is up a small climb into a short rift ahead, followed immediately by a 5 metre climb up into a higher level above.
The higher level contains more stal decorations including a large stalagmite, soon reaching a bolt traverse at roof level, rigged
from spits on the right wall, starting just after some flowstone which almost blocks the passage at floor level.
Shortly afterwards is a traverse over a hole down, followed by a 5 metre pitch to a lower level, where each branch soon ends.

Continuing along the main way through Squirrel Rifts II, the passage appears to end after 40 m, but shortly before the end,
a climb up in the roof leads to a higher level continuing in the same direction, which soon enters a large chamber with stal and
cryostal protected by tape to the right. Continuing ahead, the passage soon drops down a step to end just beyond a taped off gypsum
snowdrift. Just before the step down, a 4 metre climb above reaches Life On Mars. This can either be entered through a narrow squeeze
to the right shortly before the top, or by climbing to the top then dropping down to the right, bypassing the squeeze.

From here, Life On Mars begins as a series of domed chambers, with distinctive solutional etching. The way on is initially quite
obvious, passing through low sections between the chambers. Just after passing below a natural rock bridge, a passage down to the left
is the main way on, but the passage ahead can also be followed, passing through a low dig, and swinging down to the right to
reach another chamber, which is blind at its far end. To the right at the point of entry, however, a narrow rift passes through a squeeze and down a small climb
(tricky on the return, climbing up into the squeeze), to a wriggle around boulders leading into another chamber. All ways on soon
degenerate and become too small, with a low passage on the right at the far end being the longest.

The main way on starts crawling sized and soon enters a standing-height enlargement. Passages ahead-left and through
an eyehole ahead immediately join and end, while the way on is a rift up ahead-right. Immediately, it splits, with a low
passage on the left being one branch, and the continuing rift being the other. The left branch soon passes a too-tight
connection to the other branch to the right, with its way on being to the left. This zig-zags repeatedly, via an awkward
section where the level must be carefully chosen in the rift, before passing some proto-shark fossil spines, and entering
a large domed chamber. Ascending the chamber, it is best to take the undercut ahead-left to reach the next chamber, rather
than heading directly to the left, as the roof is loose. A narrow passage at the far end of the chamber soon reaches a climb
down to a bedding with stal decorations, where the way on closes down.

The right branch soon reaches the first traverse, requiring a sideways thrutch along the widest part of the rift,
some distance above the floor. At the end, a hole at floor level to the right gains the next traverse. This passes
through an eyehole and turns right into the final traverse. These three traverses are very demanding, and require a
great deal of effort to avoid slipping down the rift. The third is the tightest, only a little wider than squeezing size.
The passage then becomes more normally awkward, with occasional ascents over jammed rocks, before suddenly entering a large
domed chamber, with the way on to the right. This then descends into a large domed section, which has some short side
passages at the far end.
On the right at the far end is an archway into the next domed chamber, which has a short side passage to the right
which may be followed by mistake on the way out. To the left is the end of the chamber, where there is a very low side
passage, while to the right of this passage is the way into the continuation of the domed chambers.
This passes through an enlargement to reach the final chamber, with its obvious terminal boulder choke.

Crystal Maze

(With thanks to Tim Francis, MCG, for corrections.)

This begins with 90 m of crawling and thrutching to reach a step down at a dry cascade.
Just after this, a junction is reached with the normal way on up a ledge to the left,
while the rift continues to the right through some crawls as an alternative oxbow into
Pontypool Or Bust (POB) Passage.
Following the normal way on, the passage swings right through a low enlargement to
reach an obvious junction of crawling-sized passages, with The Swim on the left, and Pontypool Or Bust Passage on the right.
The Swim quickly enters a sandy floored chamber containing the Hanging Basket
helictite formation. To the left passes through another chamber before ending in mud fill.
To the right lowers to a sand swim which ends at a dig after 50 m.
Pontypool Or Bust Passage can be followed for over 100 m, with the oxbow back to the Crystal Maze entrance passage on the right,
and a few other blind side passages. Just before
the end is an awkward squeeze leading to the small SOB Chamber. A tight squeeze and crawl
then enters a larger chamber. On the other side, 20 m of crawling then reaches a
smaller chamber, and final dig which continues for about 75 m.

Perseverance I and Fault Chambers

This area is the key to several major series, including the Long Round Trip, and the entire southeast area of the cave.

From the side passage in Perseverance II, Perseverance I begins as a walking sized passage.
The roof lowers a few times, and an oxbow is passed to the left, which may be inhabited by bats
in winter (please respect any tapes). After this, a passage hidden
in an alcove up to the left is a tight flat-out crawl back to the Nunnery (the original way in).
Some side passages on the right along here lead through a small series called the Rabbit Run back into Perseverance II.
One passage in this series enters Going Square after some very tight crawling. Continuing along
the larger passage, a hairpin bend to the right precedes a scramble up boulders into Sugar Cube Chamber with
The Sugar Cube boulder jammed in the ceiling, at the other end of which is an inlet at a left bend, with a side passage ahead at the bend.
The inlet is often used as a drinking water source, though the water has not been
tested for purity, and unofficial water collection bucket and bottles are normally in place there.

Warning: in 2017, a loose pillar of stacked rocks on the left wall at the corner immediately
before the inlet has visibly moved, and several of the large rocks are liable to fall if touched.

On the other side of the inlet (to the left), a short climb leads to the top end of the
large Fault Chambers. High on the left here a smaller inlet enters that eventually
makes its way, along with the water from the other inlet, into Agent Blorenge II. The
Fault Chambers are a series of large chambers with a dip of about 30 degrees. The
lower chamber, accessed through the large opening at the bottom of the boulder
slope in the first chamber, is called Rift Chamber. Two other main side passages
lead off Fault Chambers, Elliptic Passage at the top end of the chambers, opposite
and slightly lower than the way in (the usual way on), and Fault Rifts at the far end of Rift Chamber.

The first part of fault rifts is a tall rift passage which quickly reaches an 8 m
climb up to a platform. The climb is unprotected and slightly awkward, so the more
usual route in is via Going Square. For this reason, the rest of the route is
described as part of that section.

Elliptic Passage and beyond

Elliptic Passage can be followed for some 300 m of 4 m high and up to 5 m wide
passage, passing several short side passages, to a boulder ruckle.About two-thirds
of the way along this a muddy crawl low down on the left is the start of the route
into the Wyvern Extensions, and the Long Round Trip.The ruckle can be easily passed through a walking-sized
hole to the right. Past this, a short section of passage leads to a real choke. A side
passage on the left here (Lucky Thirteen Passage), accessed by following the left edge of the choke, leads to a
hole down to the right in a small chamber. This enters a further small chamber after
a few metres of crawling. The way on from here is to the right along a crawling, later
walking, passage which leads after about 100 m to a larger passage at Big Beauty
Junction.

The Wyvern Extensions - Wessex Series

Wyvern Hall and the Main Route

From Elliptic Passage, the initial passage leads north as a muddy crawl. This ends
after a few metres at a small climb down. From the bottom of the climb, a few side
passages lead off (the ones on the right enter a small complex) but the way on is straight ahead into Dead Bat Passage. This quickly lowers to a flat-out
crawl. The passage becomes walking size after 30 m where some short side passages lead
off. One of these on the left, containing a small stal flow, is the main way on.
The route ahead, however, soon enters a 5 m diameter chamber at the top
of a 4 m climb up boulders. To the right in the chamber, the complex side passages rejoin, while
ahead-right, a slot between boulders enters an undercut. To the left in the undercut
reaches a junction where to the left enters the Dragon's Lair, but this is not the normal route into it.
To the right at the junction passes through some very unpleasant crawls sometimes half filled with water, and a couple of
chambers, to reach a tight, wet crawl to the scaffolded climb up to the Ogof Drws Cefn
entrance. Use of this entrance is strictly prohibited by the landowner and the cave
management group. This area is also a very active bat roost, so should be avoided.

The side passage on the left 5 m before the climb up into the chamber, beside the
small stal flow (not the one at the foot of the boulder climb into the chamber), can be
followed along 20 m of stooping-crawling passage to a point
where it enters a wider area with the roof at standing height. Ahead, this enlargement
enters a further large, but low, chamber with a flat roof, the Dragon's Lair.
To the right here chokes with the alternative route in tucked into an alcove on the right,
while to the left lowers before a slope down is reached. The slope enters a large, but
low, chamber with some straws in the roof, Wyvern Hall. The taped route here splits in
two. To the right it enters a hole down through boulders to a stream (but the stream
cannot be followed), whilst to the left leads round to the left of the chamber. Where
the taped route turns right, an inlet enters from a 4 m high, 4 m wide, passage on the
left, partly obscured behind some large boulders, which is the main way on. The taped route continues past this to enter another high level chamber.

The inlet can be followed for about 50 m to a chamber, S.O.U.P. Dragon's Kitchen, with the only way on (of any real
significance) being through a crawl to the right, and entering a complex area of rifts.
The Main Route begins as a crawl/stoop with a relatively easy squeeze, The Trowel, to a seeming dead end after
some 40 m.

From here the way on is a climb up a tight rift above. At the top of the climb, the
route doubles back over the top of the climb. This enters a somewhat larger rift with
the way on in a tight rift to the left, which passes a cross-rift then joins a parallel
rift to the right. A short, tight drop must be negotiated before the passage becomes a crawl.

At the end of the crawl, a junction is met. To the right a climb down enters a tall
chamber known as The Garden. In The Garden a tight rift rising to the right can be
followed to enter Awe Chasm 13m off the floor (see the section on Republican Plot),
whilst a hole in the floor enters the start of Gore Blimey (a part of Republican Plot)
and has become the more common route into here (see the same section). To the left at the junction just
before the climb into The Garden, the passage passes over a small depression in the
floor and along a rift to the left into a chamber with several ways off, an area known
as Isotonic Weirdways. An aven at
the first junction in the second side passage to the left here can be free-climbed
(with care) to enter Pasta Best (again, see the section on Republican Plot). Most of
the other routes lead to the same place but the easiest route is straight across the
chamber and under a stooping height arch. This enters a further chamber. To the
immediate left and right, the other routes from the last chamber enter, whilst the
two main ways on from the chamber are both further off to the right. A route into
Pasta Best (see the same section as before) is located in a slot under a wall to the
left whilst directly ahead, a crawl leads into a rift passage which can be followed
for about 80 m to almost enter Lucky Thirteen Series.

The two main ways on both begin as rifts and are beside each other. The left-hand route
quickly reaches a 7 m climb down into The Land Down Under, whilst the right-hand one is the Wyvern Extensions Main Route, which
continues as a comfortable sand-floored rift, and is the way on for the Long Round Trip.

The rift passes many cross rifts and side passages but the way on remains obvious until
a semi-tight squeeze is encountered between boulders, Psychology Rock. Shortly after this is a slight
turn to the left after which a tight trench develops in the floor, which descends to a junction with a
cross rift, Timney's Turn. The way on is to the right where the rift passes over some holes in the
floor to Republican Plot (these are dangerously slippery and should not be used). After
crossing the first hole a rift to the left must be taken. This quickly reaches a crossroads.
A right turn here reaches a further junction where the Main Route continues to the left.

To the right instead is a side passage which quickly enters a chamber. Continuing across
the chamber, the rift ahead/right loops back into the Wyvern Extensions Main Route, while the
rift ahead has a small side rift to the left. This can be followed round to the right
in a low passage. The height increases at a turn left as the passage passes over a
blind hole in the floor (Beware, don't fall!). Across the hole, a low passage to the
right can be followed to a second hole down. This can be free climbed to enter
Presidential Mayhem (a part of Republican Plot), but is not the normal route into that area.
The passage continues above the hole, to connect with a side passage from the Wyvern Extensions Main Route
shortly before Psychology Rock.

Back at the junction in the Wyvern Extensions Main Route, ahead is a slope up and
to the left is the continuation of the original rift. At the next crossroads, the
Main Route turns right, but to the left reaches a 12 metre climb up to a blind,
decorated chamber called Afternoon Delights.
The Main Route then meets another junction after just over 50 m. To the right another slope
up connects to the slope up at the earlier junction. To the left the obvious way on is
taped off to protect the stal flows down its walls. This taped section is bypassed by
taking a narrow rift ahead and then taking a very narrow, ascending rift to the left, to
emerge in a higher level rift. Doubling back to the right, a side rift ends after 100 m, close to Headache in Fault Rifts.

Ahead-left, the way on regains the Main Route rift just beyond the taped off section, with the way on ahead-right. (It is advisable at this
point to check the route used to enter this rift as it can be confusing on the return.)
Alternatively, a lower passage continuing on the other side of the Main Route oxbows back to the Afternoon Delights crossroads.

The continuation of the Main Route soon enters an enlargement/chamber with a side passage
to the left. This side passage forms a series of oxbows totalling around 200 m in length, and reconnecting
with the Main Route later. The Main Route continues
ahead-right over a short traverse.

This passes some side passages before entering a larger section of passage where the side
passages enter from the left. This larger section is short lived and enters a low passage
to the right. This passes through a crawl before regaining the rift at a junction. To the
left oxbows over a pit in the floor into the larger section of passage, opposite the way
into the low passage (this route is taped off in the larger passage). Ahead, the way on
soon enters Ponderosa chamber (also known as Cairn Chamber), where some stal is almost encircled by tape in the floor. Ahead the way
on soon closes down. Two passages to the left unite to become Dragon's Teeth, which can be followed for 20 m to a small
enlargement with a pitch on the opposite side, The Didgeredoo. This enters Interesting Times
(see below), and is the way on for the Long Round Trip.

In Ponderosa, two passages double back to the right, one
above the other. These unite at the higher level to become Mark's Garage.
This can be followed through a section containing delicately
positioned stal (take care), Nothing, to where it branches after 30 m.
The right branch ends after 70 m.
The left branch reaches a very loose 4 metre pitch, Death on a Twizzle Stick, dropping to 25 m of passage.

The following section can be very confusing on the return and it is advisable to continually
check the route of entry on the way in.

Also in Ponderosa, a passage to the right (to the left of Mark's Garage) enters a cross rift after a few metres, called Come Back You Bastard. To
the right, this enters Mark's Garage at the lower level, while to the left is the
way on.

This enters a small chamber after just over 20 m. Up ahead quickly becomes a flat
out crawl past delicate formations (Pond Life) and passes through an extremely tight squeeze
to enter The Whitehouse (also incorrectly referred to as Anthodite Chamber). This chamber contains large
amounts of anthodites (aragonite crystals crossed with helictites) in the roof and an
impressive 3 m high stalagmite boss in the floor.

In the small chamber, a passage to the left, Pond Passage, can be
followed for about 100 m of crawling and stooping to enter a more shattered area with
some very small calcite flake stal formations, ending soon afterwards. Just before the stal, a hole down to the left reaches a 0.5 m
high narrow rift to the left, while further back from the stal, a low passage to the left is
the 'Easier Route'.

The Easier Route swings left and passes through a tight section before enlarging,
turning right and ducking under an arch to join the other route in an enlargement, where the way on is to the left.
The alternative narrow rift route can be followed for over 20 m of tight passage of a similar nature to
reach an aven, which can be climbed to reach a larger passage, where the Easier Route joins from
the left.

The larger passage (which has a badly shattered ceiling) passes through a
shattered section before entering Yanto's Grotto (also known as the Blue Room).
This chamber contains unusual blue formations over a large amount of one wall. To the
left here, a climb up over boulders (not recommended) and a route under them unite before passing through a hole
low in the right wall into a section of passage with a fine collection of anthodites. This passes through
a smaller hole (take care to avoid damaging the anthodites) to reach a dig, with an
awkward climb up above it into a roof passage. To the right this
contains the 50 cm blue Coldfinger stalactite and 20 cm blue stalagmite formations, the
largest blue formations in the cave, while a climb up into the top portion of the passage accesses the route to the
left. This reaches a climb down into an enlargement where the only possible way on is
being dug. To avoid damaging the Coldfinger, it is best to view it from the point of
entry into the roof passage; the passage closes down completely just beyond it.

Republican Plot

The hole from The Garden (see the section on the Wyvern Extensions Main Route) descends through
relatively stable boulders to reach a short drop into a passage. To the left is a sandy
crawl which leads into Presidential Mayhem while to the right, the passage quickly
enlarges into a tall streamway, Gore Blimey. As the passage is enlarging a sandy crawl to the right is
the route into Awe Chasm. Just beyond this, an inlet enters from the right, and about 10 m
further on flows out to the left, where the passage ahead closes down.
Shortly before this point, a passage to the right above a constriction is about 30 m
long. A rift further on almost connects with the 30 m long side passage. A rift even
further on, opposite where the stream flows out, is about 20 m long and connects through
an extremely awkward and tight constriction to the 30 m long side passage.

The stream can be followed downstream along a 50 m traverse. The route passes through some
old stal and later a crawl which can be bypassed (only on the way in) by dropping down to
floor level and taking the stream route to the left. Where the traverse ends, there are some
short side passages to the left and ahead, but the stream route turns right and passes
through a complex section and a tall chamber before it becomes too tight. A passage in
the roof to the right of the chamber can be followed through two chambers to where it
becomes impassable.

The route into Awe Chasm begins as a crawl, but the floor drops quickly to give a standing
height rift. Ahead, a tight rift passage can be followed to make a tight loop with the
inlet. To the right, the way on turns left and ascends slightly to enter an enlargement.
Only the passage ahead left can be followed far. This quickly passes an outlet which passes
back under the passage but becomes too tight. The water re-enters at the inlet. Just beyond
this outlet, the source of the stream is entered, a 40 m high fluted aven, Awe Chasm.

Several routes lead off from Awe Chasm. Up ahead, a slope of rocks can be ascended to a
further slope but is blind. Up ahead/right, an undercut is blind. To the left is Blessed
Pork Scratchings. Almost directly above the way in, an almost invisible rift is the end of
the tight rift from The Garden in the Wyvern Extensions Main Route. Beside and above that is
another more obvious rift. This is Pasta Best. At the same height as the rift from Pasta
Best, but oposite the way in, another rift also enters Pasta Best. High in the roof, a
stream enters but this has yet to be reached (work continues). Awe Chasm cannot be
free-climbed.

Blessed Pork Scratchings is a well decorated passage and has formations in extremely
vulnerable positions so great care must be taken. After about 10 m, the taped route
ends and if you must procede, step in the footprints of the original explorers to prevent
damage to the delicate mud floor. The passage ends after 50 m in a choke which lies below
Headache in Fault Rifts, but which has been intentionally left unconnected to protect the
formations.

The sandy crawl into Presidential Mayhem emerges into a larger passage. Passages to the left and
above end in a chamber and chokes, and passages in the wall ahead are blind.
The way on is to the right, becoming a 15 m traverse with a stream in the bottom.
The floor steadily rises to become a sandy passage, turning left then right into a rift.
To the right, some openings enter a short oxbow. A few metres along the rift, a
squeeze between rocks on the left enters the original part of Republican Plot. Ahead, a short
section of passage ends under an aven which may be free climbed into one of the Wyvern Extensions Main Route's side passages
(described above).

The original part of Republican Plot opens up quickly to stooping height. Ahead/right
a crystal adorned passage cannot be followed far. Ahead/left, the way on continues past
a taped off oxbow to the left, two short side passages to the right and a hole up to the
left into the Wyvern Extensions Main Route before it enters a decorated section. Please take
extreme care as the stal is in a very vulnerable position. The way into The Land Down
Under is blocked off just after a 1 m high column, Ice Cold In Alex. Please do not pass
this formation as there is nothing to see beyond.

Pasta Best was originally reached by bolting up from the tight rift in Awe Chasm but as there are other
routes into Pasta Best, it is unlikely that any fixed aids will be left. The slot under
the wall of the chamber containing the climb into The Land Down Under (in the Wyvern Extensions
Main Route) is narrow but quickly enters a somewhat larger passage. The obvious route passes
unstable boulder slopes up to the left, before narrowing down to reach a tight crawl which
can be passed to enter a blind chamber.

The free-climb into Pasta Best emerges in a rock floored, stooping height passage. Back
over the climb, a loose but low enlargement is blind. A passage to the left when facing
this enlargement can be followed to reach the top of a loose boulder slope. Two routes on
below here reach the tops of the loose boulder slopes in the other part of Pasta Best.

The other route from the free-climb initially heads away from the Wyvern Extensions Main Route
and swings left to enter a decorated chamber. The formations have not yet been taped so
please take care not to damage any. To the left in the chamber, a narrow rift reaches a
pitch back into the Wyvern Extensions Main Route, just after the climb down into The Garden. To
the right in the chamber, a tight rift eventually doubles back to the left to make an
extremely tight connection with Awe Chasm, over 20 m from the floor. Diagonally across
the chamber, a climb over some boulders drops down into a rift passage. The rift descends
quickly (spits are in place for bolts) to the head of a 20 m drop down the second half of
Awe Chasm. This drop can be descended without getting too wet, although no fixed aids are
likely to be left.

The 7 m climb down (the Didgeredon't) into The Land Down Under is aided by a fixed handline
(as of July 1999) and reaches a small chamber with one passage leading off ahead, as
well as two holes in the floor to the left. The holes lead down to a very short section of
intermittent streamway, but the passage is a better prospect. This route begins by enlarging
to walking size although large amounts of stalagmite flow and columns must be carefully avoided.
The passage then lowers before a grill of stalagmites block the way into a passage to the left.
To the right of this passage, a narrow rift is the best route on. This quickly enlarges, passing
a route back to the left to the other side of the grill, before entering a small, decorated chamber.

Two passages lead off from the chamber. Across on the far right-hand side of the chamber,
a short section of passage leads to a 2.5 m column. The route here is taped off but is
accessible from the far side so please do not cross the tape to see what might lie around
the next corner! To the left from the decorated chamber a walking height passage passes a
very delicate set of straws and columns (pass with extreme care!) and over a hole in the
floor to a very small stream to reach a junction. To the right will be described below, while
to the left reaches a corner to the left to the stream. The passage now continues as a tall
rift, passing several formations, before it becomes more arched and finally ends at the Barite
Choke.

A flat out crawl beginning between some formations on the right at the first left turn along this last section enlarges
quickly and can be followed for over 100 m through many large sections, with several side passages on the right which end
below some oxbows in the Wyvern Extensions Main Route.
Meanwhile, passages on the left before Barite Choke oxbow back to the side passages behind the stalagmite grill.

The passage to the right mentioned above can be followed to a small decorated chamber from
which the way on continues as a very well decorated passage where great care must be taken
to avoid damage to the formations, including a crystal pool called The Billabong.
This eventually reaches a flat out crawl into a chamber. Ahead-right a further
chamber-enlargement is entered. To the right, a passage containing a small stream can be
followed, passing through a few tight traverses, to reach the 2.5 m column mentioned earlier.
In both of the last two chambers, small holes to the left enter a larger side passage - the hole from
the second chamber passes through an extremely tight squeeze.
This side passage can be followed to the right for about 70 m, passing several side passages
and oxbows, to a very tight section. Beyond this, a slope up enters an area of cross rifts but
all routes close down within 20 m. One of the side passages on the right, about 30 m along, has a
connection back to the passage with the stalagmite grill, as well as some oxbows of its own.

Interesting Times and The Long Round Trip

The Didgeredoo pitch drops from the Wyvern Extensions Main Route down into Interesting
Times. It is in two main sections, each about 10 m, with a 2 m climb in between. These
are aided by a fixed handline (as of September 2017). The pitch is very tight and ascending
it is almost impossible without the aid of a rope and ascending gear (jammers or prussik
loops minimum) - allow at least 15-30 minutes for each person to ascend. There are loose
chockstones near the top, these should not be relied upon, despite their convenient
position. Check if the handline is still in place before attempting this trip.

At the bottom, two walking sized routes lead off. The first of these would be ahead when
facing the head of the first section of the Didgeredoo pitch, the second would be to the
left (when facing into this second route, the Didgeredoo pitch should enter on the left
side of the passage), and is the usual way on.

The first route soon enters a small chamber, and immediately degenerates into a few silted
rifts. One ahead-left from the point of entry has about 100 m of passage with a loop, and
one ahead-right from the point of entry can be followed for about 30 m via a larger section.
Where it ends, a roof climb reaches a short continuation.

The second route (the main way on) from the bottom of the Didgeredoo pitch soon turns left twice,
passing entrances to a side passage on the right at each turn, before it enters a small chamber with several alcoves
on both sides. A tight squeeze in the final alcove to the right enters a 100 m long side passage,
with several side passages of its own. The main way on, however, is the
obvious passage on the opposite side of the chamber, which quickly lowers at a junction where some bat bones are taped off, and a short
side passage is ahead-right. The way on to the left at the junction then reaches another junction with more bat bones, where both routes
can be used, but the left one is best, to avoid a stalagmite in the right passage.
After the passages rejoin, the way on passes through two relatively easy squeezes, to reach a stooping
section. After this, it passes through a crawl with a shallow keyhole slot in the floor, to reach a
small rock bridge. At this point, a side passage to the right is the way on for the Long Round Trip.

Continuing ahead over the bridge instead, the passage soon splits into several passages and oxbows containing rock pillars and chokes
(affectionately known as the Land of a Thousand Pillocks). Following the main way through these for about 50 m,
the passage then turns left and lowers over rock slabs, before rising again, and turning right to end at a choke.
A small passage on the left has a hole to the right, passing through a smaller section to reach a
low chamber and terminal choke.

The small, tubular side passage to the right at the rock bridge enlarges into a small chamber, with the way on
being the walking sized passage on the opposite side. Passing some formations, the way on is to the
right at a junction, becoming another crawl alongside some stal. This passes some raised drip pocket formations, referred to
as the 'mushroom' formations, in a sandy section. After passing through a rocky S-bend, it enlarges and reaches a
junction.

Attractive stal columns adorn the passage ahead-right, but the passage beyond them soon ends in a low, sandy crawl.
Instead, the way on is to the left at the junction. This starts as a rift, then enlarges as it passes
a low side passage to the right, and becomes a flat out crawl over a mudbank ahead. The low, wide passage ahead
soon ends, and the way on instead drops into a hole on the right, which then swings left. When the passage splits, the way
on is through a squeeze ahead-right. At the next junction, the way on is to continue ahead, which emerges in the chamber
at the end of Haggis Basher Number Two, with the way out immediately to the right.
Haggis Basher can then be followed to rejoin the normal Round Trip.

The scope for further developments in this area is significant as there are still many side
passages that have not been dug.

6. The Southeast

The Lucky Thirteen Extensions

Gone With The Wind

To the right from Big Beauty Junction quickly leads to a chamber on the other side
of the Elliptic Passage choke, while to the left leads into Gone With The Wind. This begins as a 2 m
high phreatic arch with a sandy floor and continues like this for about 100 m, to an area with many
gypsum "cornflakes" decorating the roof, walls and floor. Here, the passage
becomes more square-shaped and the sandy floor gives way to a rocky one. Gone
With The Wind ends after a further 150 m, where the passage ducks down under a
low shattered arch (pass with care). This is the start of the Midwinter Chambers,
and is the usual route to Dollimore Series, Sleepcrawler Series and War Of The Worlds.

Within its first 35 m, Gone
With The Wind passes two blind alcoves tucked into undercuts on the left,
followed by a
walking-sized alcove on the left, where the small Station Thirteen Passage
leads off (the usual route to Gone In The Years and Big Country).

Note; the choke near Big Beauty Junction has a good water supply, and the floor at the start of Gone With The wind
is soft sand, making this a good camping location for long term digging trips.

Midwinter Chambers and Going Somewhere

Midwinter Chambers consist of a succession of chambers separated by short
crawls over rocks and gravel. The rock in this area is in thin, slate-like, layers. This
results in a very loose passage roof! Much of the Midwinter Chambers are adorned
with hanging "forests" of gypsum crystals or large mounds of "snowflake"-like
gypsum on the floor. After about 100 m of these chambers, the arched passage of
Going Somewhere leads off to the left, and is the usual route to Dollimore Series,
Sleepcrawler Series and War Of The Worlds, but the Midwinter Chambers continue to the
right. These are much as before, and reach what was once a seeming end after about
75 m. A hole to the right here now enters the Northern end of Upbeat in Hexamine
Highways. Also at this point, a dead-end passage doubles back to the left but a flat out
crawl in the floor leads through a few small chambers into a somewhat larger
chamber. On the far side of the chamber, a low passage on the right is Hexamine
Highway. This passes some short side passages before a 1.5 m step up enters a
shattered, crawling sized passage. At the end of the crawl, a hole down to the left
enters a squeeze, marking the start of Hexamine Highways.

Going Somewhere takes a right turn past a side passage straight ahead after just
over 10 m. The roof lowers before rising again not much further on. The way on
turns a few corners with the roof lowering and rising on several occasions before the
passage then turns a corner to the left, passing some short side passages on the
right called Sign Of The Beast, and enters a larger passage after a further 30 m. This is Snowball
Passage. To the left is the alternative way out via Rogered Senseless and Gone in
the Years South, while to the right leads along the main part of Snowball Passage.

Hexamine Highways

Once through the tight squeeze, the passage becomes somewhat larger than before
but this is short lived as the passage passes over some gypsum in the floor, The Hexamine Block, and then
ascends a steep rubble slope into a narrow, shattered passage. After a short distance
this opens up again and it is necessary to slide down a small rock slope under a
toppled stack, The Leaning Tower Of Pisa. The passage then gradually enlarges and
passes a short side passage to the right. Ahead, a step up is reached. At this point a
tight tube heads off to the left while Heartbeat continues ahead. The tight tube enters a
larger passage which passes through the easy Dismantled Choke and a tighter section before
reaching a junction, Walls Too Good To Be True. To the left is Worm Hole Series while to the right enters a larger
passage after 20 m, Death By Kangadile, which heads to the right. This passes Top Hat Passage on the left
before reaching a dug out crawl after 30 m. The crawl ends in a dig where a severe
lack of oxygen makes digging hazardous.

Top Hat Passage is 60 m of walking-crawling passage, passing through the Top Hat Turnon squeeze after 30 m, and
ending at a very tight squeeze and choke. This is very close to Pick-A-Stick Aven in the
Last Sandwich.

For the first 60 m, Worm Hole Series consists of several small chambers and walking sized
passages, intersected by tight crawls. About half way along, it passes small side passages
on the right, and at about 45 m along, a side passage on the left ends close to Exodus.
Between those two sets of side passages is a wormpile-like fossil in the roof.
Near its end, it has a proto-shark fossil spine (like the ones in Raiders Passage and the Entrance Series)
visible in the ceiling, which is one of the most southerly known in the cave.
The main passage then drops into a lower level. The lower level is blind back beneath the crawl, but
continuing in the same direction that the crawl had been heading, the lower level soon passes a choke
to reach a much larger chamber. Facing into the chamber, two passages ahead lead into a blind chamber.
From the chamber, the only way on is to the left along the crawling sized Bee Keeper's Passage,
which has some honeycomb-shaped fossils. After 15 m, it passes through a squeeze into Satan's Knockout,
passing a blind side passage to the left. This passes through more squeezes into a rift, ending
too tight after 30 m, close to Pick-A-Stick Aven in the Last Sandwich.

Heartbeat passes through a squeeze to reach a T-junction. To the right, a walking
sized passage lowers and passes through a squeeze before reaching a T-junction
after 40 m, Crunch Corner. To the left here is Downbeat while to the right is Upbeat. Upbeat passes
several boulder obstacles to reach a junction after 40 m. To the right closes down,
while to the left passes an oxbow before becoming very shattered. This smaller
passage reaches a loose hole up into the Southern end of Midwinter Chambers after
50 m having passed several side passages and oxbows. This route into Midwinter
Chambers is loose so care must be taken if using it.

Downbeat continues in a straight line, with several roof tube oxbows, to reach a chamber after 50 m,
Camp Coffee (with The Bed on the left). A side passage
to the right here, The Toothpaste Tube, has been dug inconclusively. Across the chamber, an unentered
oxbow with multiple rock bridges is Draebridge Rift, while to its right, a crawling
sized passage can be followed for 70 m through a tight section into Trunk Passage, a low enlargement
with anastomosis on the ceiling. A side passage on the left shortly after here, Squat Martian, becomes too tight.
Continuing past Squat Martian, a further tight section and a small chamber lead to the final dig, Channel 4.

Climbing up above Crunch Corner, a small roof tube, The Gerbil Run, leads off. Early on this reaches a
very tight, 5 m long squeeze before becoming small crawling sized, and it is possible
to turn around if needed. It passes some small gypsum formations,
The Frozen Gerbils, before swinging left, and reducing in size. 10 m along here, it
then passes through a tight squeezing section, into a larger passage; Submission Passage.
Ahead-left, the passage passes a delicate calcite raft formation, Gerbil Heaven, before
ending in a chamber with helictite decorations. To the right in Submission Passage,
a squeeze enters the continuation of the large passage. This passes over a pit in the
floor, and ends after about 60 m, passing some short side passages.

Warning: the squeezes in The Gerbil Run are exceptionally tight, and even
small cavers will find them uncomfortably awkward. It is important that you ensure you can get
through before entering each squeeze, as it is not possible to back out when you are part way
through them.

Gone In The Years

Station Thirteen Passage leads from the alcove in Gone With The Wind,
through crawling-stooping passage, with a choice of upper and lower oxbows early on.
At a junction later on, the way on continues as a crawl to the left,
while to the right is a short side passage. After 100 m,
Station Thirteen Passage reaches the large passage of Gone In The Years, which leads left and right. To
the left is Gone In The Years North and to the right is Gone In The Years South.

Gone In The Years North reaches a choke after 75 m, passing an oxbow into Gone In The Years
South on the right almost immediately, and a few other side passages later on.
At the choke, a short side passage can be accessed through a tight eyehole on the right.
A small stream flows out of the choke and down an impassable hole in the
floor, joined by another stream from an aven. By following the small stream that flows through the choke upstream,
the choke is quickly passed. Once through, following a small passage to the right
and then taking a crawl to the left regains the somewhat larger passage, with the main way on ahead.
On the left, an arched side passage can be followed through a series of crawls,
ending just after a choke, with a dead-end chamber above the choke.
The main way on passes under some low arches before it reaches a junction,
where the way on continues to the left, to reach another junction.
To the left, a low arch enters a 50 m long crawling-sized side passage which ends abruptly at a blind rift,
while the larger passage to the right is the way on. This passes
over a rubble bank into a continuation of the passage with a side
passage on the right which oxbows to a side passage two junctions back. The way on is straight ahead over a further
rubble bank into a chamber at the start of the Big Country Extensions.

Gone In The Years South also continues past a few side passages to a crawling-sized
tube. This is quite short. Large passage then continues for about 250 m
where it splits into two. The upper passage is a walking-stooping passage over
boulders, while the lower passage is flat-out. These two passages are about
100 m long each and eventually join through a hole through boulders at a choke.
Two other passages can be accessed through the choke, the 75 m long high-level
Gone In The Head, and the much longer, low-level Rogered Senseless. This is
entered through a 5 m long tight crawl and can be followed for about 400 m through
larger passage with an undulating floor to where it enters the even larger Snowball
Passage.

Snowball Passage

This is named after a large (football-sized!) ball of gypsum near its start. At the
point of entry from Rogered Senseless, Going Somewhere leads off to the right, whilst the small hole to the
left is the original, but less commonly used route, into Sleepcrawler Series. Snowball Passage is more commonly
entered via Going Somewhere, where the usual way on is to the right, with the original way into Sleepcrawler
Series being a hole in one of the alcoves opposite.

Snowball Passage is about 100 m of large boulder passage. The Snowball formation is soon seen on the right,
where there are short side passages on both sides. The taped route soon passed through an oxbow down to the left,
before rejoining the large passage. It then passes a series of crawls on the left called The Pentangle, after which
Snowball passage passes under a balcony. Immediately afterwards, a slot to the right is the start of Exodus,
the way to Dollimore Series.Snowball
Passage continues ahead up a rocky slope, becoming lower, and soon passing a small side passage down to the left called The Fly Trap.
The passage soon splits, with the left branch ascending to a choke. A small alcove to the left of the choke
passes down through the edge of the choke (proceed with care!) and enters the end of the Black Run, the usual way into Sleepcrawler Series.

The smaller right branch loops back round into Snowball Passage, 20 m back from the choke and a few metres above the
floor at the top of the balcony (many people find this loop confusing and visiting cavers should take care not go
back on themselves when following it). Halfway around the loop, a side passage called I Buried It In The Sand
leads off to the left, providing an unusual and tight way into the Last Sandwich.

Exodus leads to a reasonably large, gypsum-decorated passage.
This continues for about 50 m (passing a section known as Mayhem
of Pillars) to where the Last Sandwich (the way to Dollimore Series) leads off to
the left. 50 m further on, Exodus splits into three at Southern Cross. To the
right fills with mud after about 50 m, very close to Worm Hole Series in Hexamine
Highways, whilst both to the left and ahead lead to dead ends after about 15 m.

Last Sandwich

The Last Sandwich is a smaller passage than Exodus, with a few low crawls over sand and rocks.
During the first 150 m, a few side passages are
encountered, the most notable ones being on both the right (Upper Sandwich) and left after about 50 m, which lead through very tight connections
into I Buried It In The Sand, which enters the loop at the end of Snowball Passage. At
the 150 mark, a junction is met. To the right enters the loose Pick-A-Stick aven
where a small passage at the top chokes close to Worm Hole Series and Top Hat
Passage in Hexamine Highways, while to the left, the Last Sandwich continues
more as a stooping/standing passage with fewer crawls. This passes several side
passages but the main way on is always the way straight ahead. After a long 150 m,
the passage dips down through a gravel squeeze before picking up again, through
two more squeezes. The second of these ends at a slope up and emerges in the
floor of a 1 m high, 2 m wide passage with the only way on ahead. This is the start
of Dollimore Series.

The main side passage on the right about 100 m after the junction with
Pick-A-Stick aven, can be followed for 150 metres to an end, close to Pisspot Passage in Dollimore Series. The much shorter passage on the left
at the same point is known as Little Hedgehogs.

The Big Country Extensions

Many of the passages in the Big Country Extensions are well decorated and so
great care must be taken. This is especially true of Poetic Justice.

The Route Into Big Country

The initial chamber of the Big Country Extensions (see the section on Gone In The
Years North above) has two ways off, either of which may be used to reach the main way on, but the
Right Hand Side is generally easier.
The Right Hand Side is a passage under an arch to the right, while the
Left Hand Side is hidden behind boulders ahead-left, and passes over boulder obstacles to
join the Right Hand Side in a chamber. The Right Hand Side passage swings left through a crawl,
passing an oxbow to the left, to reach a large balcony, with an even larger chamber down a climb to the left.
The main way on is down the climb (at the right edge of the balcony) into the chamber,
at the bottom of which a passage leads back under the climb into Three Amigos!

Several side passages also lead off around the balcony and chamber.
Ahead and right at the balcony (from the point of entry), three passages join and
continue to reach an inlet waterfall. To its right is a deep rift,
which can be climbed down with care, but is blind. Just after the deep rift, a side passage to
the right reduces to a very small crawl, ending after 50 m at a dig. Continuing below the waterfall,
the passage splits into three, with the left and centre routes ending quickly, and the right one being a
stooping sized tube which passes through a choke into a large, dead-end chamber.
At the top of the waterfall is a chamber
with a short inlet to the right, and a larger inlet ahead which closes down and ends in a choke, with a side
inlet up a pitch to the right ending in a very long, muddy wallow in the stream. The waterfall's aven has
6 unofficial
M10 bolts in place, which can be used to attach hangers and ascend the pitch, but which may have rusted beyond use.
The inlet pitch has more M10 bolts in place. An aven in the chamber has also been scaled
via a bolt traverse, but there is no further passage at the top.
Back at the balcony and facing into the chamber, to the right of the climb down, two low passages in alcoves
join to become a flat out crawl. This passes a passage to the left and continues to reach a junction.
To the left is blind, while to the right ends at a choke below the floor of the earlier dead-end chamber.
Back in the chamber below the balcony, a large passage to the right ends abruptly,
where a low passage to the right reaches the previous flat out crawl.
Meanwhile, the Left Hand Side passage enters from ahead in the chamber.

Three Amigos! starts as a 30 m long chamber, at the start of which an inlet
enters from the left. Where the chamber narrows down, short side passages
lead off ahead and to the left, while Three Amigos! turns right before
turning left into another chamber. On the left is a decorated alcove. Directly across
the chamber, two side passages lead off, the right-hand of which is larger and well-decorated,
and either of which can be used to reach Nervous Breakdown. To the right of these
passages, a further decorated passage is the way on, which can be followed through some crawls and
stoops to a stooping-walking-sized passage. After 30 m from the chamber, it passes an alternative crawl
into Big Country on the right, which is longer and larger than the usual route with a few
flat-out sections and climbs, but which is taped off to protect
its formations, which are in very vulnerable positions. The usual way on is to
continue ahead along the stooping-walking passage until it closes down, 50 m after the chamber.

A small tube on the right here, Slaughter Canyon, leads
along a flat-out crawl. After about 40 m, a tight awkward squeeze (larger cavers may
find it very difficult or impossible) called The Canyon is reached, in a keyhole shaped section. This is
followed by a further 50 m of crawling to emerge in the wall of a huge bouldery
passage, some 15 m wide and 7 m high, Big Country. This large passage, but
which is surpassed in size by War of the Worlds, MSAD and Into The Black(!), contains
one of the largest streams in the cave and heads in both directions.

The two passages that lead towards Nervous Breakdown join and become a single, decorated passage,
which reaches a narrow rift after 120 m. It is best to stop here, but continuing ahead, the rift
reaches a squeeze over a rock into Nervous Breakdown. Passing through an eyehole,
a second squeeze at head height to the left is tighter than the first, but may be bypassed with a crawl at floor level.
From here, there is a side passage ahead, while Nervous Breakdown swings right into a shattered passage,
which is about 75 m long in total, and typically crawling height.
The passage roof is often very loose and is best not touched. The walls are often similar.
After dropping through fallen slabs, it passes through a squeeze into a more
rifty style passage, but the shattered passage quickly returns,
with rocks referred to as the Sword Of Damocles, and the roof referred to as Damocles' museum. A committing head-first descent
into a rift then reaches the last few metres of breakdown passage, to a terminal choke.
The side passage ahead just after the bypassed squeeze ascends into a
more stable rift, First Man Standing. To the right ends in Nervous Breakdown's collapse, while to the
left reaches a low, wet section after 10 m, ending in a dig.

Warning: Nervous Breakdown is very loose, and should be treated with great care, or simply avoided.

Big Country

To the left leads upstream for over 100 m to a junction. Big Country continues to the left, ending in a choke after just 65 m.
At the junction, The Hangman's Creek is the large inlet ahead-right.
80 m along it, a 2 metre climb on the right enters Hangman's Oxbow, which leads to Blorenge Oxbow
via about 100 m of crawls and stoops, passing some side passages on the left, the last of which is about 80 m long.
The Hangman's Creek continues past Hangman's Oxbow, passing up through a hole into a large chamber. High on the left is a short side passage called Klondike,
just past it on the left is an inlet passage, and ahead is the continuation of The Hangman's Creek. The inlet on the left passes through
a choke into a blind chamber, with a continuation dropping back to the stream before ending in a choke.
The way ahead in The Hangman's Creek soon splits, with the stream on the right passing through a choke to end at another choke.
The passage on the left also carries a small stream, which emerges from a narrow rift. The continuing passage,
Hobo Humpin' Slobo Babe, soon splits in a small enlargement. A way on to the right passes through a squeeze
and degenerates into a series of crawls. A way on to the left in the enlargement reaches an aven with no way on at the top,
and about 30 m of passage at the bottom.

To the right from Slaughter Canyon, Big Country leads downstream for 150 m,
passing the other end of the alternative crawl on the right about half way along,
above the rubble bank opposite some stalagmites, to
a large junction. To the left is the Blorenge Inlet (described later), while ahead-right
is the continuation of Big Country. About a further 50 m downstream a small side
passage leads off on the right, which can be followed for 100 m to a larger passage,
which ends in mud fill to the left, and chokes to the right.

Big Country continues beyond the side passage with its boulders giving way to wet
mud banks. After about 100 m, it enters a very large section with a boulder floor, where a lake forms in flood conditions.
Hidden behind rocks on the right, a drop down enters a large, mud-covered inlet passage nearly as big as Big Country itself, which ends after 80 m in mud fill,
passing a fault chamber on the left. Big Country continues large until, after a further 100 m, it finally closes down. A hole in the floor to the
right is the way on. Straight ahead, however, small hole dropping behind boulders on the right leads to a series of
small passages, Canyonland, which soon splits in two. The way ahead soon splits, with each branch soon ending.
The way to the left reaches a 6 m pitch down beside a waterfall, with a short passage to the right from the bottom.
The pitch can be climbed with care, but because of the friable rock, a ladder is recommended, rigged from the unofficial hanger above the pitch.

The hole down to the right leads immediately into a large arched stream passage,
the continuation of the Big Country streamway. To the right, upstream, passes over
several mud banks before choking after 100 m. To the left, downstream,
the passage widens and passes over similar mud banks and past muddied formations to reach
a wide area, where there is a series of small side passages on the right.
Staying up to the left avoids a tricky climb up a mud bank.
Ahead the passage returns to its smaller size and passes over yet
more mud banks to a sandy area. At this point, a sandy alcove to the left enters a
short side passage. Ahead, a low section enters a much larger continuation of the
stream passage. From here, the passage becomes larger still as the roof rises
and the boulder floor rises to meet it, forming a large choke estimated at about 20 m
wide and 15 m high. At the top in roughly the middle of the choke, a rift heading
back towards the passage can be used to ascend to a chamber within the choke.
A further ascent through a hole leads up into a chamber above the choke, where there
are some fine anthodites in an alcove to the left. This is the present limit of the downstream cave. From here, the water
flows south for over 8 km to the Snatchwood Bridge and Pontnewynydd risings.

Blorenge Inlet

Blorenge Inlet carries a stream as large as the Beyond A Choke streamway but is
a rather smaller passage than Big Country. After 40 m, a large bedding
at head height on the left enters the start of Blorenge Oxbow. Blorenge Inlet
continues for 50 m, passing the small Flat Bat oxbow to the right,
to reach a junction, where Blorens Inlet enters from the right.
Blorenge Inlet continues ahead-left for 175 m to an ascending choke, just after a
house-sized boulder which is lying in the stream.
On the right side of the choke, an ascent through loose boulders
reaches a slot down to the right into stable passage. Ahead soon closes down, but to the left
reaches the choke again. A climb up through the choke from here enters Poetic Justice, offering
a possible round trip via Blorens Inlet (see below).
20 m after its junction with Blorens Inlet, the low Oxbow en Blorenge begins on the
right side of Blorenge Inlet, with several entrances back to Blorenge Inlet over the next 70 m.
Starting at the same point, several small passages on the left side of Blorenge Inlet
all connect to Blorenge Oxbow, with those after 70 m forming a maze of crawls connecting with Blorenge Oxbow.
The last side passage on the left is the main exit from Blorenge Oxbow, just before the house-sized boulder.

Blorenge Oxbow begins stooping to walking size, with large amounts of gypsum on the walls.
Just after a stal flow on the left, the oxbow splits in two, with a stream running in the left
branch. The left branch is taped off at first to protect the gypsum, but can be accessed more easily through the
next side passage on the left after another 45 m, where side passages on the right connect back to Blorenge Inlet.
The two branches then run parallel to each other, each being stooping size with occasional crawls,
with several bedding connections between them. At one point, the stream in the left branch flows in a rift,
with a larger oxbow to its right.
Part way along the left branch, a keyhole-shaped inlet on the left is the end of Hangman's Oxbow. Starting around 65 m along the right branch, side passages
to the right form a maze of crawls connecting back to Blorenge Inlet. 100 m along either branch,
they rejoin in a wide, low area. Side passages to the right are the last of the maze of crawls.
Continuing along the old main direction from the wide area, the passage turns sharp right after 30 m, with a
side passage to the left, before it rejoins Blorenge Inlet for the last time.

Blorens Inlet is a rather monotonous, keyhole-shaped,
and gypsum decorated inlet passage. After 75 m, it passes a series of oxbows on both sides,
followed by another set of oxbows on both sides after about 200 m.
At 225 m, the short Mineral Passage leads off on the left.
30 m further on, a major side passage leads off on the left, Poetic Justice, and just beyond it is
a chamber. The chamber is richly decorated with elaborate helictite decorations, the finest
in Big Country.
The continuing inlet is Boys From The Black Stuff, which passes through a choke and continues as a degenerating passage for a further 200 m,
splitting into parallel branches after 75 m, and ending at a choke in the right-hand branch.

Poetic Justice passes an oxbow on the right after 40 m leading to Boys From The Black Stuff, and reaches a major junction
after 65 m, with the Poetic Justice Extensions ahead. Poetic Justice continues to the left, past a series of
small oxbows, to reach a large fault chamber after 80 m.
In the floor on the left, a hole down through the rocks leads into a small, stable passage,
where a right turn leads through the loose choke into the end of Blorenge Inlet.
From the fault chamber, Poetic Justice continues down to the right, gaining a stream, to a cross junction with the short
Tombstone passage to the right, which climbs to twin chokes. Continuing ahead past Tombstone,
Poetic justice turns right to end after 50 m, with a very tight side passage connecting to Satanic Verses. Continuing ahead at the right turn is Mn Mud Inlet,
which splits, with each branch soon ending.

Poetic Justice Extensions starts with a junction, with the passage ending ahead, a wide passage
to the right, a narrow passage to its right, and the short Swinging Climb passage above.
The wide passage turns right then right at the next junction. It then passes a connection to the
narrow passage on the right, and turns left to reach a T-junction. To the right at the T-junction is
Poetic Justice III, which ends after passing a connection to the narrow passage on the right,
which also connects back to Poetic Justice. To the left passes a connection back to the earlier
wide passage on the left, and reaches the Satanic Verses chamber after 40 m, where a very tight
passage to the left connects with the end of Poetic Justice, and a passage to the right ends after less than 50 m.
Satanic Verses contains stal in very vulnerable positions, and is best not entered unless the stal can be protected in some way,
such as being shielded with clean plastic sheeting.

Dollimore Series

MSAD

The passage from the Last Sandwich contains some gypsum crystals and reaches
a short crawl after 20 m. At the end of the crawl a hole up enters a wide area with
a steep boulder slope down into a 10 to 20 m square, boulder floored passage,
More Singing And Dancing (at least, this is the
"acceptable" name for the passage).

To the left, the
passage rises up a boulder slope before descending into a stream. The passage
continues 5 to 15 m high and wide, past several formations, and can be followed for over
400 m to a choke in the floor of the Reactor (see the section on Sleepcrawler Series).
The stream in this passage is assumed to be the one seen flowing in the passage
north of the Reactor. Just before the end of the passage, a spectacular Pagoda
formation can be seen to the left (confirmation of its name is being awaited, but
it is often referred to as the Snowy Christmas Tree). On the first right bend,
a climb up a cairn into a roof tube on the left gives access to 90 m of crawling.

To the
right along MSAD, the large passage can be followed for over 300 m to a junction
with a smaller passage to the left containing a stream, Out Of The Blue. This part of MSAD contains many sections of passage larger than War Of
The Worlds South but as it does not hold these dimensions for long enough, it is
difficult to ascertain which is the larger passage. The author's personal feeling is
that War Of The Worlds South should be considered as the larger.

At about 150 m along MSAD (Right), at a point just before the first 20 m by 10 m
opening (!!!) at the top of a boulder slope to the right, a passage to the right at
the base of the slope is the Clique. This mud-floored passage can be followed for about 40 m until it
degenerates into a series of choked rifts. The opening at the top of the slope is
the beginning of Screaming Like A Stuck Pig, a 5 by about 7 m passage that is
very remeniscent of Elliptic Passage. This runs parallel to the remaining 150 m
of MSAD with several openings or passages into it. The passage ends at a 15 m
pitch into the Hall Of The One (see later). About 5 m back from the pitch, a flat out
crawl to the right, about 3 m from the floor, enters the 300 m long Pisspot Passage passage, which has its own view
down the pitch to the left. A small continuation to the right becomes a narrow rift which turns right after 40 m,
to reach a junction after another 20 m. Ahead descends to mud fill, while the way on is to the left.
This becomes a flat out crawl, taking a parallel passage to the right when it becomes too small ahead.
At a junction, right drops down a climb to a blind rift, while the way on is ahead-left through a squeezing section,
which soon turns left then right, before reaching a much larger section of passage, where there is a side
passage to the left leading to Nicola's Grotto Landing. The larger passage is short lived, and the way on
becomes a narrow rift again, soon reaching a cleft on the left, which drops down a 6 metre pitch into a short side passage.
The pitch appears to be free climbable, and there are no available ways to safely rig it - the top is very loose and showers rocks down the pitch.
Above the pitch, the way on continues small, eventually ending after another 100 m in a choke,
aiming towards Hexamine Highways, and passing close to the Last Sandwich
side passage. The side passage to Nicola's Grotto Landing starts stooping/walking sized, taking a bedding ahead at the end.
The bedding passes through an awkward squeeze down into a rift to reach a chamber.
On the far side, a bedding crawl continues to reach Nicola's Grotto Landing.

To the right at the junction with Out Of The Blue, MSAD continues larger than before
and enters the largest chamber in the cave, Hall Of The One, with several ways off.
The chamber is about 40 m long, 30 m wide including the landing, and between
15 and 20 m high - this is only 5 m wider than Lamb and Fox Chamber, but is
much larger in terms of open volume. To the right,
Screaming Like A Stuck Pig enters from 15 m up the wall, while to the left a route up
a boulder slope provides the main ways on. From the top of the boulder slope, a
climb up the scree slope to the right, keeping to the left of the large rock pinnacle (The One), reaches the Nicola's Grotto Landing and to the
left, another small slope up reaches a much smaller passage, Luck Of The Draw, while
ahead, a 4 m roped climb down enters Into The Black. Fine collections of helictites may be
seen via each of the last three ways on.

A small slope down quickly enters the stream passage, this being about 4 by 4 m,
roughly circular with a rift in the roof (occasionally, opposing mud banks give the
passage more of a diamond shape), dimensions which it holds for its entire 1.1 km
length. Over the first 400 m, many displays of straws and stalagmites are on view
with two areas of exceptional displays of helictites and straws. For the length of the
streamway, most of the walking is done on the streambed. This can become very
tiring and so trips to this area should not be underestimated. At the terminal choke,
a short side passage on the right is Farting Welly Rift.

Nicola's Grotto Landing & Passage

Please take great care when visiting this area not to damage the delicate formations.

From the Landing three passages lead off. To the left, a descending passage passes through
a series of rifts to a chamber with several digs, one of which connects via a 3D maze to Catlitter Crawl
in Dog-Leg Complex. Some distance over to the right, the walking-sized (Nicola's) Grotto
Passage reaches an area with some small formations. Passages to the left and right here
also end in digs. Ahead, a flat out crawl enters an enlargement with some much better
helictite formations, Nicola's Grotto. A passage continues to the left here and appears
to end at a choke. A route under the choke enters an area with yet more helictite
formations, these being somewhat dirtied. Ahead, 10 m of stooping passage enters another
grotto. This has a collection of some very fine helictite formations. The way on beyond
closes down so please do not enter the grotto, as the best view is from the point of entry.

At the far end of the landing, continuing along the landing beyond (Nicola's) Grotto Passage
reaches the bedding crawl which connects to Pisspot Passage.

Into The Black

The climb emerges at the top of a steep boulder slope in a large chamber, at the
bottom of which a further slope enters yet another adjoining large chamber.
Together, these chambers are equal in size to Hall Of The One. To the left, a
steep 20 m slope up boulders to the left reaches Dog-Leg Complex, while to the
right here a large passage containing both of the aforementioned streams leads
off. This passes spectacular sedimented mud banks and cliffs with the stream
flowing in between. On its 400 m journey to a choke, the passage passes many
smaller side passages, only two of which, situated about 100 m and 50 m before
the choke on the left, can be followed very far. The first (100 m before the choke),
Yellow Van Passage, begins as a 4 m square passage and enters a small
chamber after 20 m. Two ways lead off, a low passage to the right and a slope up
then down ahead. These two routes unite and continue as a large passage for
100 m to end at a draughting muddy choke. The second side passage begins
small and branches several times, totalling 200 m of passage with several climbs.

The choke at the end of Into The Black is the current limit of the downstream cave.
From here, the water flows south for over 8 km to the Snatchwood Bridge and Pontnewynydd risings.

Dog-Leg Complex

The collections of helictites in Dog-Leg Complex are, alongside those in Luck Of
The Draw, amongst the finest in the British Isles and great care must be
exercised to avoid damaging them. A selection of photographs are available in our
Draenen gallery.

Once at the top of the slope from Into The Black, a climb up a rift to the right
reaches a level floor, the true start of Dog-Leg Complex. 10 m along from here,
a tall rift to the right is the principal way on, though a hole at floor level
ahead reaches The Gobbler (see Luck Of The Draw), and there is a side passage to the left.
The side passage enters a slightly larger passage, which can be followed round to the left to reach a
balcony over the climb up the rift. From here, a traverse to the right (beware, the
floor and wall to the right here are very loose and some form of protection is
essential) reaches a further balcony on the other side of the hole down. On the
far side of this balcony a large alcove through a 2 m high arch ahead houses a
small passage to the right, Positive Thumg. This can be followed through increasingly larger
passage to reach a junction with Luck Of The Draw.

The principal way on reaches a junction after 5 m where a wriggle over a
boulder to the left enters an enlargement. Passages up and down ahead-right
offer apparent ways on but the real continuation is in fact through an inobvious
rift at head height back to the left. Within a few metres, this reaches a traverse
over blind holes in the floor which in turn enters an enlargement. To the right, a
crawl can be followed to reach a much larger passage, Top Banana. From here, to the
right leads to 300 m of passage passing over Into The Black (one of the passages
here, Catlitter Crawl, connects with a passage from Nicola's Grotto Landing) while
the taped route to the left enters a climb up a rift which can be followed to
reach a decorated chamber, Top Spots. The taped route turns left here into a
flat out crawl. This turns a corner to the right near its start in a small
enlargement and ends at a very tight, awkward, squeeze into a rift. To the left
here enters a chamber with four ways on.

Ahead, up a mud slope, a stooping height passage reaches a loose slope up,
followed by a crawl to reach a richly decorated chamber - one of the best decorated
chambers in the cave. It is requested that cavers do not enter the chamber as to do so would
destroy many of the formations (there is a good view of the chamber from the
point of entry, where the taped route ends). To the right in the four-way chamber, a 5 m squeeze enters 15 m of passage ending at a choke.
Also in the four-way chamber, ahead-right, a small passage containing some seriously tight squeezes enters
the other side of the decorated chamber. This route does leave many formations
very vulnerable however so, again, please do not use this route.

The other way on from the aforementioned chamber is an obvious one to the left,
beginning with a small climb up. This passes through a decorated chamber and
then a very well decorated section of passage to reach a left turn into a large
passage-chamber, Circus Maximus. At its far end, the roof on the left side is
decorated with a very fine selection of helictites. An obvious passage at this end
of the chamber can be followed though a narrow rift to enter another helictite
decorated chamber. For the best view here, a passage to the left just before the
chamber can be followed round a corner to enter the chamber (please take great
care). From here, there is no way on.

To the right of the Circus maximus, also at its far end, a series of holes enter
Rainbow Canyon. This passage takes an immediate right turn and runs parallel
to Circus Maximus. After 100 m the passage takes a hairpin bend to the left then
one to the right after a further 100 m, before the passage degenerates into a
series of small choked passages.

Throughout its length, this passage is well decorated with mud, gypsum and calcite
formations. Please try to avoid damaging them.

The slope up from Hall Of The One is aided by an unofficial handline as of 2018, but can
normally be ascended and descended without needing a handline, if required.
Luck Of The Draw begins as a large bouldery passage, with liberal amounts of
damp mud. At its start, a complex of small oxbows lead off on the left. After 75 m, or 30 m beyond a series
of arches, a side passage on the right, Positive Thumg or Panda Hunting, enters the Dog-Leg Complex.

The main route is generally walking-sized and continues as such for over 1.2 km.
Early on there are many intricate calcite formations, starting with some helictites in the ceiling, after 150 m.
Just afterwards, at a bend to the left, some stalagmite and helictite formations on the right are The Pineapple Patch.
After about 1 km is a section
of passage containing what must surely rank amongst the finest collection of
helictites in the British Isles, Medusa'sChildren. An equally
impressive display of helictites can be found in Dog-Leg Complex. Approximately
100 m beyond this, a further chamber is encountered. This has an unusual
formation in the roof, the Lightbulb, as well as many helictites.

Some 100 m further on, Luck Of The Draw turns sharp right and lowers to a crawl,
swinging left then taking the right branch when the passage forks. At the next fork, there
is a standing height chamber to the right, which is the way to Cantankerous Surveyors' Passage,
while Luck Of The Draw continues to the left.
Although the crawl ends a short distance afterwards, it sets the scene for the next 700 m; a
mixture of crawls and stoops which get progressively lower! Relief is provided by
the occasional standing section, though these become less frequent over the last
350 m.

Beyond the crawls the passage becomes walking sized for some distance, and ends shortly after two small chambers, with a single side passage
on the left just after the crawls reaching a dig. All possible
continuations pinch out or end in mud fill. This part of the cave is unlikely to interest
any but the serious prospector or insane masochist!

Throughout its length, Luck Of The Draw has several side passages over 100 m in
length. A short side passage doubling back on the right before Positive Thumg is Negative Thumg.
A short side passage on the right after Positive Thumg is Glitz.
A side passage on the left after 130 m is Whinger, about 100 m in length.
The first major side passage is on the right behind The Pineapple Patch, taking great care
to pass the very delicately placed formations. This is the Gobbler, and is a
series of gypsum decorated chambers interlinked by rubbly crawls. Near its far
end, the earliest of the many real side passages to the right, Pomegranate, reaches a climb
down. From the bottom, 30 m of passage reaches the early portion of Dog-Leg
Complex.

The other principal side passages are situated around Lightbulb Chamber. To the
left about 100 m before Lightbulb Chamber is a passage which reaches a dig after
100 m. Just before entering Lightbulb Chamber a passage leads off to the right and
reaches another dig after some 30 m, whilst ahead, as the passage turns right out
of Lightbulb Chamber, is a more substantial side passage which enters a chamber
after 200 m. To the right and ahead from here are digable leads which are currently
being pushed.

Cantankerous Surveyors' Passage

Starting at the standing height chamber in Luck Of The Draw, a crawl in the floor
at the end of the chamber leads into a walking-sized passage after a few metres. The route takes a rift to the
right after about 15 m, which zig-zags and ends after 30 m in a much larger passage,
with unusual solutional features. To the right,
a walking-sized rift passes through a climb and some short crawls to end 15 m into
a crawling-sized phreatic tube. Ahead is a small oxbow while to the left the main route
continues large, passing a shortcut to Geryon's Lair via a slope on the left.
The main route reaches a choice of routes at a circular chamber up to the
right and an archway to the left, which is the main way on.

Immediately after the archway, a passage doubles back up a slope to the left. This
enters the Geryon's Lair chamber with a large and impressive helictite formation in the roof,
The Geryon. Several other routes off this chamber lead back to the main route.

The main and circular chamber routes rejoin 20 m after the archway. Several side passages on the
left reach a maze of small passages, while the main way on
turns right then left into Needle Passage, passing some more oxbows and short side passages on both sides.
Several small piles of gypsum are encountered, as well as a 40 m long side passage on the left.
At an obvious junction with a large oxbow and small side passage on the right,
a pile of gypsum in the floor contains The Needles, several selenite needles as much as 25 cm long.
25 m further on, the oxbow rejoins and the main way on reaches a chamber. To the right, a crawling
passage can be followed through a small constriction for 100 m. To the left, the
passage enters a further chamber after about 30 m where there is a side passage tucked in an alcove on the left,
and another way on is through an undercut ahead. This ends at a dig after 15 m.

Sleepcrawler Series & War Of The Worlds

Sleepcrawler Series

The small hole opposite Going Somewhere in Snowball Passage passes through
several squeezes and down some small climbs before, after some 100 m, it
enters a series of stoops and crawls, Don't Go Skiing, with a high level connection
to Red Chamber. The more usual method of entry is through the choke at the end of
Snowball Passage from where The Black Run heads off in an Easterly direction.
This reaches a choked area after 100 m where the way on is through a low section on the right,
which then swings to the left and lowers before entering Red Chamber. Hidden in an undercut to the right, a very low
passage with lots of gypsum crystals, Gypsum Link, oxbows into Lost In Space after 100 m, but this is not the usual route.

Heading straight across Red Chamber a crawl under the wall enters a wide but low
passage containing a large bank of gypsum. Here a small
hole to the left reaches a climb down into Don't Go Skiing. The wide passage reaches
a seeming end after 30 m but a hole through boulders to the left enters a short
series of passages, A Shallow Grave, while to the right another hole through boulders
enters a low passage, which is the main way on.

The roof quickly rises to standing height and a chamber is reached. To the right here is the
end of the Gypsum Link oxbow to Red Chamber, and is easy to mistakenly follow on the way out.
To the left, a
short passage reaches a small ramp up boulders marking the start of Lost In Space, the main way on.
This can be followed for over 750 m, with each large section containing drifts of gypsum and cryostal.
When the passage enlarges after 25 m along here, a rift in the roof on the left is Tom Cat Alley,
which leads back into Gypsum Link (mentioned above). Over the first 500 m along Lost In Space, several
areas are met where the large passage is split into sections by low crawls and tight
squeezes, some of which are not obvious. One of these tight sections is located to the
left just before the passage chokes but regains the large passage quite quickly. A short
distance on, the taped route forces the caver to enter a smaller passage to the right,
containing several rock pillars. This regains the large passage at the bottom of a small
drop.

About 20 m from this drop, a climb overhead enters the way on as ahead chokes just
past some formations. The climb overhead enters a small passage to the left,
Intergalactic Overdraught. This turns many corners before it once again enters the larger
passage, which has more examples of cryostal. The passage now continues with fewer tight obstructions than before until,
30 m past a side passage up a loose climb on the left, it appears to close down, with a taped-off oxbow up the ramp of rocks ahead.

The passage up the loose climb on the left, Killer Tomato Crawl, is 300 m long and well decorated with
gypsum but cavers are requested not to enter the passage to protect the gypsum floor and walls from
damage. At one point there is a squeeze, after which gypsum crystals cover the floor of the passage for much of its length.
One of the piles of gypsum on the floor, a small ball of gypsum fibres, is known as the Killer Tomato.
Several similar formations have already been seen along Lost In Space, so this particular one is not really
worth damaging the other formations for, and the passage is best left alone.

Back in Intergalactic Overdraught, just before the final boulder slope which leads up to the taped-off oxbow, a low passage - one wall lined
with boulders - leads off to the left. This enters a passage much larger than before,
Cold Fusion Passage, where the oxbow reconnects from above. The passage passes by a large rock covered in gypsum, The Washing
Machine, and several other formations on the right (The Camberwell Carrots), before it climbs up into a very wide area with more cryostal. Following
this, the passage shrinks and becomes very narrow. This narrow section ends where
a climb up boulders enters a huge, high-roofed chamber, The Reactor,
the second largest in the cave.

To the right the fault-controlled flat wall is covered in pale green flowstone, while ahead
the end of the chamber lies some 60 m away with no way on. To the left, however, a large
alcoved section of chamber enters an area where the wall has peeled off to reveal a large
passage at the base of a 25 m high boulder slope. The boulder slope is very loose and
must be descended with care. At the base, the large passage, Destiny Inlet, can be followed for 100 m,
with the stream seen intermittently between the boulders, until it reaches the site of a
former camp. From here, a smaller passage provides the only way on, passing several old
formations, to reach a large corner to the right after 100 m. Just before this, a hole up
enters a passage that leads back to the top of the camp. This passage has a fine collection
of intricate helictites that are (and hopefully will remain so) in pristine condition, the High Camp Treasures. From the
corner, the taped route crosses over a large boulder and down a short climb to reach a
steep boulder ramp. The ramp makes a considerable climb before it reaches a large
junction. The huge passage to the right is War Of The Worlds (WOW) South, whilst the
somewhat smaller passage to the left is WOW North. These are both inlet passages. Just before the
junction, a short passage to the right (appearing as a double-alcove) contains some fine helictites.

War Of The Worlds

War Of The Worlds North enlarges over the first 75 m to become a very large passage,
although by no means as large as its southerly counterpart. After over 100 m, water
enters from a small inlet on the right to flow south, back along the passage. After a
further 150 m, the passage bends round to the right and soon ends at a large choke.
At this point, a 2 m climb to the right enters Sendero Luminoso. This passage begins
crawling size and passes a few formations, but further along the passage, the
formations become much more intricate. Once the formations end, the passage lowers
to a 50 m sandy crawl before it finally chokes, some 200 m from its start.

War Of The Worlds South begins very large and almost immediately reaches a
junction, where the very obvious War Of The Worlds South continues to the right,
and a mud and boulder slope up to the left enters the fault controlled Golden
Handshake Rift (see below). At the junction,
War Of The Worlds South is an impressive 19 m wide and 15 m high, making it
Britain's second largest passage. It continues as such, along the same fault that
controls Golden Handshake Rift, for over 400 m, passing cryostal deposits on the right and some large helictites high on the left wall.
Beyond this the passage roof begins
to gradually lower until, having passed 3 muddy passages on the left (Soups Of The World), the passage
chokes.

The stream emerges from under the left wall, just before the choke. Above where the
stream emerges, a tight route can be forced to a climb down in a narrow rift. This can be
more easily gained by following the stream until the stream route becomes too tight.
At this point a crawl to the right gains the same narrow rift. The rift becomes lower and
enters a stream passage, Blood River, with the stream flowing from the left into an impassable rift on
the right.

Heading upstream, the passage turns right before a side passage enters on the right.
This only reaches a muddy aven. Continuing upstream, the way on is to follow the left
most stream. Other routes are passed to the right, some of these contain streams but
no way on. Two crawls in the stream are then necessary (Warning: this area is
rather loose) before Prisoners Of War is entered (see below).

For most of its 150 metre length, Golden Handshake Rift (formerly known as Menopause Rift)
has walls covered in gypsum crystals, which can easily be damaged by passing cavers,
so should be treated with great care. It soon passes down a somewhat tricky climb, and later turns
right at a junction to reach a rocky ascent reaching a stal formation and terminal choke.

Soups Of The World has three entry points along War Of The Worlds South, each
leading into areas with untouched mud deposits - great care
must be taken, and cavers should avoid passing through connections where the mud is undisturbed.
The first entry point is obvious and very wide, with a wet mud floor and mud
drip formations in the roof. Early on, a smaller passage on the left enters a wider section which ends in
muddy tubes ahead-left, and passes oxbows to reach a choke to the right. Continuing along
the wide passage soon reaches another choke, with a muddy side passage on the right entering a low chamber.
The way on ahead connects to the second entry point. The second entry point is an obvious tube leading
into a small enlargement which swings left. To the left is the connection with the first entry point,
while to the right it connects with the third entry point, but this connection has been left unentered.
The third entry point is a wider passage than the second, and ends almost immediately in mud fill, with
an unentered window on the left looking into the second entry point.

Prisoners Of War

Several passages in this series contain delicate mud deposits and have been taped off.
These are either oxbows or have no way on. Please respect the tapes and also avoid
areas which look as if they should have been taped but which have not been.

About 10 m beyond the crawls, two passages to the right (the second of which contains
a stream) unite and become Route 1. Ahead is Route 2.

Route 1 begins as a low, very muddy, streamway but quickly becomes walking-sized
before reaching a junction. To the right the stream inlet becomes impassable. To the
left the route becomes somewhat lower with two side passages to the left. These
enter Route 2 (see below).

The way on continues to where it gains a stream flowing in the opposite direction to
the last one. This stream brings with it some entertainment in the form of thick
glutinous mud! A rift on the left here also enters Route 2. The passage turns right and
then loses most of the stream to the right. From here the stream makes its way to
the earlier inlet in Route 1.

The passage now enters a chamber. To the left, another passage enters Route 2. To
the right is a black aven with some red "seaweed" patterns on the rocks. To the right
of this aven the way on continues through a cross rift with some mud lacework on the
rocks. The way on then becomes smaller and 100 m further on enters a low phreatic
area at a junction. The stream flows off to the right where it cannot be followed. To the
left, several small side passages are passed on the right (these are oxbows into the
passage about to be met) before a junction is met. To the left is where Route 2 enters.
To the right the passage lowers, passes the side passages mentioned above, and
enters a 5 m wide by 3 m high passage. This is the continuation of War Of The Worlds
South and is called Peace In Our Time. To the right chokes after 20 m having passed
some black avens. A pool below one of these contains some interesting black
doughnut-shaped mud formations. These are black versions of the strawberries in
Strawberry Passage. To the left the passage climbs up a loose slope (take care)
where it can be followed for 50 m through one low section to a choke.

Route 2 begins low and wet. 75 m along is an inlet to the right. Ahead is Route 3 but
it is recommended that one follows Route 2 along the trench in the inlet.

Route 3 soon enters a chamber at a choke. From here there are two routes on. These
are an obvious route up through the first section of choke and a hole up to the right.
The route up enters another chamber. On the right here is a shattered continuation.
This reaches a junction at a short climb up over a boulder with a passage to the right.
Up over the boulder a narrow route enters two further chambers. There is no way on
from here. The passage to the right reaches a junction with a very low passage to the
left and a scramble up ahead. This enters a chamber. To the right here is the
aforementioned hole up to the right at the start of the choke. To the left, a tantalising
way on is taped off. The only way on from here is the very low passage. This enters a
rift passage with a chamber to the right where Route 2 is met.

From the trench, Route 2 becomes larger with two side passages to the right. These
enter Route 1. The way on to the left becomes larger and enters a chamber where
Route 3 enters from the left. Up ahead is a secondary part of the chamber. The way on
from here is up to the right. This enters a wider area where the only real way on is
ahead. This becomes an easy traverse followed by a climb down to the left. At this
point a hole down to the right enters Route 1.

Continuing ahead, another hole entering
Route 1 is encountered. This enters Route 1 near the black aven. The passage turns
left at this second hole and quickly reaches a junction. Ahead a wide passage enters
the climb down to the left with many short side passages. To the right is very
complicated. The best route here is generally the left most choice of routes. This
ends at a junction in a smooth phreatic area. To the left chokes. To the right reaches
an aven with some more red "seaweed" markings on the rocks, Seaweed Aven. Ahead
a junction is reached. To the right quickly reaches the final connection with Route 1,
whilst to the left a small slope down enters Blue Blood Streamway, that is presumed
to be the source of the Out Of The Blue Streamway in Dollimore Series. To the right the
streamway narrows before choking. Several small passages on the left are oxbows
with tight side passages and avens. Heading left in Blue Blood Streamway reaches a
choke after 75 m. At the point of entry into Blue Blood Streamway a very muddy, narrow,
rift ahead enters an aven after 20 m.

Tackle

All major routes in the cave can normally be followed without needing tackle.
However, some routes rely on unofficial handlines and fixtures which are not officially
maintained, and visitors should consider bringing their own.
